    About 3 weeks ago I finished my planned mods to the TA-N77ES.  They were delayed about a month due to an error that I did.

    I incorrectly connected a pair of wires & fried a pair of final output transistors.  Working too late into night the has its hazards, I guess I was more tired than I thought.
    The final output of the TA-N77ES is quite interesting.  Each channel has 3 pairs of transistors in parallel.

    Part of schematic showing the 3 pairs of final output transistors for the laft channel.


    The amp functioned after disconnecting the damaged transistors.  I also disconnected 1 pair of transistors in the other channel & ran the amp like this until the replacement transistors arrived.  Sound quality seemed just as good with the 2 pairs of transistors disconnected.

    I replaced the damaged transistors plus 1 pair of transistors in the other channel.  I replaced the pair of good transistors in case there would have been any imbalance between the channels.

    Other mods:

    All electrolytic caps on the protector board replaced with Nichicon KZs.

    All except the 4 big electrolytic caps on the Main (A) board with KZs or FGs.

    All except the big electrolytic caps on the Main (B) board with KZs.  The large caps on both boards tested okay.

    The input RCA jacks with Vampire CM2F-OFC RCA connectors.


    The internal wires for speaker output with 12 gauge wires, soldered direct to board.


    The incandesant lamps for the meters with diodes.  This increases lamp reliability & brought power consumption for the lamp circuit from 2A down to 36mA.  The color isn't quite correct, I will change the diodes if I can find any that are a better match to the original color.


    I did the calibrations for the DC offset, bias & power meters.  All of them were quite close before I adjusted them.
    This beast should be good for quite a few more years now.

    What an exquisite job you've done of upgrading your TA N77ES Power Amp complete with the excellent quality Nichicon KZ caps and the superb sounding Vampire CM2F-OFC Pure Copper RCA connectors! Are we going to be able to see some of your high quality pictures of this TA N77ES Power Amp?

    Yes, they will be coming.  I have not put the side panels on yet.  I the panels off so they would not get damaged while I was handling the amp.

    I did not note in the first post that I also replaced the power cord & plug on the amp.  It now has a 16 gauge power cord & Hubbell hospital grade plug.

    David_S- Your TA N77ES will sound sweet with the power cord and plug upgrade. Does it look something like this TA N80ES without its panels?

    It looks similar except for the extra changes done to the large caps on that TA-N80ES.

    The 4 blue caps in the background of that image are not the originals, my unit still has the original caps in this location.  The 2 black caps in the row of 6 foreground caps look original.  My N77ES still has the original 4 caps here, the board has space for 2 more.  All these caps tested okay.  I might later fill the empty spaces on the foreground board of my amp.

    I would like to know what the total diference in capacitance value that TA-N80ES has from it's original stock values.  My lights already dim a small amount for a short time when I power up the N77ES and the initial charge goes into the caps.


    I also put Soundcoat damping material on the back side of the metal panel behind the meters and on the top & bottom panels, not covering the ventilation slots.

    Excuse me if pigtail fuse use is mentioned in your "The AC Power Principals In Action" thread but I have overlooked that posting if it is.  I would like to know what your opinion is about replacing the in line AC "snap in" holder & fuse with an equivalent soldered in pigtail fuse.  You can answer this in the "The AC Power Principals In Action" thread if you feel it fits into that thread.

    I know of a number of highly competent Modmen to whom replacing the in line AC "snap in" holder & fuse is an important part of the upgrade packages that they offer. As you know the "The AC Power Principals In Action Thread" is dedicated to exposing and eradicating these kinds of weak links in the AC Power Delivery System the chief of which that I recently discovered and you have had a significant and highly valued input on sharing the deeper technical impact of and that is the Wall Outlet which affects all of the equipment which with the backdrop of having upgraded many power supplies with higher quality cords and plugs myself the Wall Outlet still looms as the greatest Weak Link of all and by upgrading the primary source of AC Power at the Wall Outlet to its fullest potential are all of these lesser yet highly significant and very sonically important weak links that have previously been upgraded are finally able to reveal their full Musical effect.

    You are always welcomed to bring your knowledge which is based on a wealth of practical experience as a skilled Audio Tech to the "The AC Power Principals In Action Thread"!

    Hi, the blue caps are 22,000uf 100v each for a total for 44,000uf per positive and negative rail. The 6 caps in the bank of caps are original. I only changed the smaller caps and trim pots on that board. The stock unit had 2 main caps of 22,000 80v. You can see the story here on my website:

    Maxx-Thanks for the feedback.  Swapping snap-in holders & fuses for pigtail fuses has not been high on my priority list but in the back of my mind for quite a while.  I will post it to the "The AC Power Principals In Action" thread when I swap some out.

    sonyeslover-Thanks for the cap values.

    Money...as always. They were great amps. I had them bridged mono powering my Magnepan speakers. The setup had tons of headroom, I would rarely go past 10 watts per channel peak.

    sonyeslover- I noticed the wedge and pyramid studiofoam in the background of your pictures of the Sony TA N77ES Power Amps. Are these Power Amps played along with a Preamp and front end in this room with these acoustic treatments?

    Hi,

    Iīm beginning to read some service manuals just to try to learn and I just find two caps (C501 and C503) of 22000MF / 80V each but your amp has four big blue ones...

    Any C502 and C504 I canīt find so am I blind or what?

    The other question I have is the different number of caps named C315, 316, 318 and 319 4700MF / 80V each; you have six of these - why are two of these not standard and what is the benefit of six?

    Iīm very well aware of that it is not just the size and numbers here that makes an amp interesting... but consider that Yamahas new A-S2000 2-ch amp rated 2x90 w has four 24000MF caps in its design it must be a quite nice amp of 2011?

    TMC-the amp with the 4 big blue caps is an N80ES that sonyeslover modded.  My N77ES still has the original 2 caps (C501,C503) on that board, they are encased in a resin filled metal housing.  That board has locations for a total of 4 caps.  The housing for C501 & C503 covers the area the other 2 caps would occupy.  The service manual for the N80ES has those locations that are empty in the N77ES marked as C502 & C504.




    The picture with 6 of 4700uF caps is also sonyeslover's N80ES.  My N77ES has 4 4700uF caps in this board.  The service manual for the N80ES has the other 2 caps marked as C330 & C380.


    The extra caps give each channel 3 4700uF caps in parallel instead of 2 in parallel, this reduces resistance per channel for current to/from the caps.  The reduced resistance would give the system faster response/recovery time.  The extra capacitance should also give more reserve when the unit is driven hard at high volumes or with ineffecient speakers.

    Maxx-according to what I can find on the web, the N77ES had a MSRP of $1200 (US) in 1987.  The Bank of Canada inflation calculator puts that about $2000 today.  That shows what kind of value can get if you find one in good condition.

    Maxxwire;  I didnīt intend that the Yamaha Integrated amp would be an alternative to the TA-N77ES. What I tried to highlight was that we here often write that "they donīt do these kind of amplifiers anymore" and I think that Yamaha actually shows that they still can when they really wants... and compared to other high end brands 2000US$ arenīt that much for a new amp! (The estimated retail price in my country is 3250US$ by the way...)

    If you should compare the Yamaha I think it would be more fair to look at the TA-F730ES or similiar, but that was not the reason for my post.

    Gosh what the specs are beautiful for the TA-N77ES....!

    David_S; My apologies here.... I remembered that I had seen some pictures on this forum of some amp with "big blue ones" and when I looked back in this thread I didnīt notice that the picture actually shows a TA-N80ES when the thread discuss the TA-N77ES... I had as you surely can understand some differences when I tried to cross-check the pictures and the service manual of the TA-N77ES caused of this metal housing I found in the SM. Thank you for the explanation of the use of the additional 4700MF caps, it sound interesting to know why Sony didnīt put these in from the beginning and also the same why the two big caps are extra. We are talking about the flagship of the ES-amps from this age here so I really hope that those origin customers got info about this upgrade was possible?

    Sonylover; Did you your TA-N80ES modd yourself so you can reply on the difference when adding these extra caps?

    Sorry Maxx, I must have missed this question...yes, I had the amps bridged mono, so one per channel, using my STR-V444ES as my DAC and preamp. The results were quite good when paired with my Magnepans. When the money situation improves, I will be looking to get another power amp for those. Right now I still use my V444ES, with my tube amp for power, which is seriously lacking driving 86db speakers! None the less, it does a fine job at low levels...The acoustic treatment really helps the sound.

    I modded the TA-N80ES myself, which is basically an updated N77ES. Upon looking at the service manual, it did show 4 main caps being used, but it seems only some amps got 4 while others 2, when I removed the "chemical condenser" on mine, I saw only 2. So, upon my research of the part specs in the amp, I felt it safe to install 2 more caps. Normally, I would not recommend doubling the capacitance without other mods as this can damage the rectifiers and cause a large load on the power transformer and switch at start-up.

    Thanks for the link to the Yamaha Integrated Amp I hadn't seen a wonderfully executed fully balanced design like that for awhile! I have always maintained that there are many Audio equipment manufacturers around the world that make high quality gear and its because of this more expensive build quality that they just that can't sell this premium quality gear at the same pricepoint as they used to any longer unless they choose to reduce build quality in order to maintain the same traditional pricepoint as Yamaha, Denon, Onkyo and Sony all do for their entry level Receivers that are still in the same basic price range that they were 10 years ago.

    That was not my intention either. I just thought that it was a good opportunity to post the TA N77ES' specs since this Thread is dedicated to the mighty TA N77ES.

    I learned a lot about classic ES gear through this forum.

    Yesterday evening I listened to the CCR's first self titled album using:
    CDP-X303ES (recapped) > TA-E77ES > TA-N77ES.  These units are set up on my new stand.
    What as beautiful sound.

    I still have more upgrades that will make it better.  I have a Panamax power management unit coming (tracking shows it just cleared customs).  I still have more upgrades to do for the speaker wires from the components & speakers to the wall jacks.

    The sweet sound is the entire system from start to end.  The classic Sony ES gear starts it all.

    Which Panamax power management unit will you be getting? When I auditioned MOV based surge protection/line conditioning Panamax was the only one I auditioned that was able to offer an improvement in sound quality!

    The much more expensive offerings from Chang Lightspeed, Mon$ter and Audio Prism failed to improve the sound of Audio equipment in any way. The Panamax 1000 did a great job for me for many years and since then they've greatly improved their products to help your vintage Sony ES gear sound better than it ever has!

    Maxx-I am getting the Panamax M5400-PM.  Whatever information I can find on it is positive, except for the price.  I looked at Monster, but didn't like them.

    I am getting the (new) Panamax through an ebay dealer with greater than 14000 transactions & 99.9% positive feedback.  The net saving over getting the same model locally is $170.00.  It just cleared customs back east so I expect it might take another week to get here.

    Hi,


    I have a Panamax (M4300) and I like it very much.

    Another unit to consider would be an APC H15.  It sells for ~$200.00 and is an excellent unit.  Its just another option to consider, that's all.

    Has anybody measured the temperature above their amps to see how hot the amp gets?  I am testing how hot my N77ES gets by putting a sensor directly on top of the top case.

    I am setting up a small fan behind my N77ES to keep it from overheating & help extend it's life.  I set up the fan & tested it, modified the mount for the fan & retested it.  The fan helps keep the temperature down & the modification to the mount for the fan reduced the rate of temperature increase.

    The max temperature I now measure after about 4 hours is 36.5 degrees C.  The ambient room temperature is 20 degrees C.  Im sure it will heat up some more if left on for several more hours.  I did not have time to leave the amp on longer during yesterday's test.  There is also another improvement I will be doing to the fan mount.

    What is the safe upper temperature limit?

    Hi
    I just bought some fans yesterday - Noctua NF-S12B ULN (http://www.noctua.at/main.php?show=productview&products_id=26&lng=en). I intend to use two of them, on top of my N77ES, and two of them on my N80ES. They are really silent, and rotates with 500/700rpm. I paid about 38US for them each, and bought four 9V batteries as well, one for each fan, which works really great. 
    I havenīt measured the temperature without/with my fans yet, but I think they will help keeping the temperature down.

    Your cooling setup will be much more efficient than mine.  I am using a fan behind the amp, the air flow is directed downwards towards the space between the shelf and the underside of the amp.

    The power source for my fan is a small AC adapter.  The adapter has several output voltage settings from 3V to 12V.  The fan is a 12V fan.  I am using one of the lower voltage settings to keep the noise level below audible range from the listening area.

    The adapter is plugged into the switched outlet of the E77ES.  The current draw of the adapter is so low that it should not affect performance of the E77ES.

    Mine is getting pretty hot too. Sometimes you can't hold your hand on the top cover longer than 2 seconds so I'm using two silent PC fans with regulated voltage for quite some time now.

    I also did some testing when raising the idle voltage on my N55ES. Blowing onto the transistors lowered the voltage and affected the working temperature.

    So my guess would be that cooling may affect the sound.

    Interesting, the amp gets extremely hot only when watching movies, that's when the fans come in. Pushing it hard in stereo mode makes it a little less hot.

    I also believe that heating has to do with pretty high AC voltage. It supposed to be between 220 and 230V but the instrument shows 238 - 240V most of the time ...

    I am going to go against the grain here - I am not sure additional cooling is needed for a properly adjusted and well ventilated N77ES/N80ES.

    My N80ES is raised up off it's feet about 1/2" and has about 3 1/2" of clearance above it and it gets warm but not hot, even when I leave it on for 8 hours or so. I used to have it sitting on it's feet with only 1 1/4" or so of clearance above it and it would get alarmingly warm.

    So basically what I am saying is try to do everything you can to improve air flow before you start messing with fans etc.

    Mark-The air space above my amp is less than 3 1/2".  The fan is to compensate for the reduced air space above the amp.

    I am using one 2" fan that is sitting on the shelf behind the unit,  it is blowing to the underside of the unit.  The fan is blowing at a low speed to keep air circulation going.  The fan is on whenever the amp is on.  I am not trying to have the unit running cold, but I also do not want it to cook.

    I received the Panamax M5400-PM power management unit yesterday.

    The sheet metal of the case is a respectfully heavy gauge but I also put Sound Coat damping material inside some panels.   I put the power conditioner onto the stand & plugged a few components into it.  Hospital grade plugs are a very secure tight fit into the M5400-PM's power outlets.

    A quick sound test shows it to be a definite improvement.

    I will try to do more configuration this weekend & further testing.

    I understand the concern.  I have had power bars that only allow use of every second outlet when hospital grade plugs are used.

    I used a Panamax 1000 for 10 years and when I lived on the downtown grid there was a particular spike that would blow the right channel fuse in my Conrad-Johnson Vacuum Tube Power Amp about once every 2 weeks which only that old Panamax could stop!

    It is also nice to have all the components on the stand plugged into one power management unit.  I like the combination of switched & always on outlets.  Some lower end power management units do not have switched outlets.

    I have the TA-N77ES plugged into a switched high current outlet & the TA-E77ES plugged into a regulated switched outlet.  This lets me control their power from the Panamax and saves wear of the ON/OFF switch in the TA-N77ES.

    I have other components with old style ON/OFF switches in the always on outlets.  Components that use standby power are in the switched outlets, this helps save some power.

    When I had my Panamax 1000 which must be the great grandfather of your M5400-PM in the Panamax line I also enjoyed having the convenience of a similar kind of power management only without SOTA power regulation.

    I took some photos to show the overall condition on my TA-N77ES before I put the amp into the stand.  A local friend also wanted to see what the final power transistors look like.


    The underside with final power transistors.  The heavy black, white & red wires are 12 gauge wires I put in, they go from the PC board to speaker connectors on the rear panel.


    Rear view with Vampire Wire CM2F-OFC RCA connectors.


    There was some damage to the back bottom corner of this side panel.  I was able to touch up the damage & make it look less visible.

    coffeedog- Once you get your Sony TA E77ESD/ TA N77ES up and running you will soon find yourself having very quickly posted over 100 times about how great they sound and you will then also have full unrestricted access to the Agoraquest search engine.

    I'm curious about the E77ESD's phono section. Have any of you had a chance to compare it to other phono preamps? Wondering how it stacks up . A few comments on other blogs/forums/sites have labeled it 'lackluster' etc.

         I have a NAD 1020 whose phono section is wonderfully musical and not sure whether I'll end up swapping it out.  The comparison on my own is awaiting a turntable(Mitsubishi LT-30) that I just purchased...it's in New Jersey and I am in Central NY...5 hour drive.  

             First impressions of the new Sony amp and pre amp soon... haven't had much time to sit down and fully enjoy them as I am quite busy at the moment.

    Soon soon soon   :-)

    THe replacement Meter Bulbs for the Ta-N77ES.....  Elko part # 2162   $2.00 a piece at my local electric shop
                                            They look great.

    I have not done a serious listen to vinyl using the TA-E77ES.  I previously digitized vinyl that I don't have onl CD.

    The price you have for the Elko bulbs is very good compared to what I heard Sony charges for them.  Other people have said Sony charges about $17 each for replacement bulbs.  I replaced the 6 bulbs in my TA-N77ES with 12 LEDs & series current limiting resistors.  The light color from LEDs is not quite the same as the original incandescent bulbs.

    First of all, I'm jeleous! Second welcome to AQ! Now, to answer your question, I personally do not see a problem adding those caps, but, I wouldn't. When I had my pair of 77ES amps, I did not feel the need for the extra capacitance. It did cross my mind though! It seems Sony built in a lot of extra space to the amp, including the possible doubling of the main filter caps. This combo is great and you got a very good deal, especially if mint! Congrats! Let me know if you need any assistance. Perhaps someone could advise on the banana jacks. I just recently replaced some in my receiver, but the N77ES is another animal I think. Feel free to browse some Sony ES pics and mods to my amps here:

    http://www.flickr.com/photos/mastercontrolmedia/

    Most of the ES pics are on the later pages.

    oops.. forgot to ask...
    Has anyone explored replacing the binding posts at the speaker connection to something like a banana plug or any other type connector that does not involve clamping or wrapping the bare wire onto the amp?

    HI... I am new to this group just having purchased a TA-N77ES and matching TA-E77ESD Preamp..all minty condition (Craigslist $800). The amp will be back from my service technician tomorrow..he said the values were all very close to spec and it was almost no adjustment.


       I am curious... Is the process of adding the 'missing' 2 Capacitors  (C502,C504) to their respective places simply a matter of rewiring them in in parallel with the rest of the Caps or are their other wiring mods needed. I am assuming that the power switch and circuits could take the added strain as the amp was designed for them...or....did SONYy instal barely adequate power switching commensurate with only using 2 Caps?


    I like the idea of adding the beefier speaker wiring and power cords and plug  all displayed above.
    Is there anywhere that someone has posted a comprehensive list of mods that have been done with possibly the list of parts they used?(brands/part number/specifics).
         I am currently playing through a pair of Magnepan 1.6QR's and/or Mariah LS2's.
    The upgrade in sound that I have alreayd heard before sending the amp out to be spec'd was wonderful.
          Thanks anyone that my reply, I have been reading the many posts since I bought the amp..inspiring!

    coffeedog-congrats on getting a mint N77ES, E77ESD amp/preamp pair.  That is a good price for a mint pair.

    I have also not felt a need to add entra caps to the empty positions in my N77ES.

    Hi Everyone and thanks for the greetings.

         Nice to hear that it really isn't needed to add caps. I should get the amp back ths afternoon and I am eager to hook it all up and enjoy iit. The previous owner had even detached the rosewood side panels and wrapped and stored them away..he used home made ones because they would not have been visible in his rack. They don't have a scratch on them. I had to replace the meter bulbs but found mention of a local store that carries $2 bulbs that do the job.

           Soneyeslover... gorgeous work on the tube amp in your pictures... I went to RPI and was involved with the radio station there WRPI... saw a lot of nice work and that rivals the best. Very pretty

       I've also got an old Sony PCM F1 Digital Recorder as well...we used an F1 for a lot of early digital recording of performances at the Troy Music Hall and when the chance came I bought one. i havent tried the tapes in awhile...there is no digital out so I am awaiting a good beta machine before I try the old and possibly compromised tapes.Pushed them to DAT when  the DAT machine came out.

    Max,

       That is the problem..I , as a member, am only able to view one(1) page and 10 (ten) results and not the 3(three) pages and 30 (thirty) results as you state......when I clik page 2 or 3 I get the same info you just quoted and then a reviewing of PAGE 1 (one) and not page 2 or 3.
       Though the header does switch from saying "Displaying results 0 to 10 of...." to "displaying results 20 to several"  the actual posts retruned remain the same...the first 10 posts.
    rather disappointing.

      I have posted a separate question stating this and though 30 people have viewed it...no one has a clue. I am hopeful someone might be able to figure out the work around.

    There is only 1 1/8" space between the top of my TA-N77ES & the shelf above it.

    This is the fan & bracket I made for cooling the N77ES.

    The bracket is not pretty but is out of sight behind the N77ES.

    Here is a shot of my TA-N80ES with upgraded speaker wire, 4 main filter caps and bypass caps. A little on the messy side though...

    Did you replace the 1uf caps on the Main A board (C302 and C352) with electrolytics, or did you switch to film?

    Can you give us a little guide on replacing the internal wiring for the speaker outputs?  I am trying to make sense of it from the schematic but not succeeding.  Maybe it will be clearer once I have the amp on the bench in front of me.

    Mark

    C302 & C352 - I did not switch to film.  The parts list has these as 100V caps.  The original caps tested okay & I left the original caps in place.

    The schematic does not show wiring for the speaker outputs very well.

    The red, white & 2 black wires that go through the board in the lower right corner are the replaced wires to the speaker outputs.

    Wires to the speaker outputs attach to the board at the yellow circled locations.


    Wires attached to speaker terminal board.


    More wiring improvements can still be done in the N77ES.  Maybe some time in the future when I run out of other projects.

    Thanks! It makes more sense now.

    I am also planning on doing a binding post mod - I will put in one nice set of red copper posts and connect them to the A and B outs. That way the relays are being ran in parallel, which couldn't hurt.

    I am also interested to see what you do here.  So far I have not done any binding post mods.  The N77ES will certainly benefit from a binding post upgrade.

    So I started on this last night and its clear to me that theremismno way in hell 12 gauge wire will fit in those holes on the speaker board. Did you pull strands off until the wire fit in the hole?

    So I started on this last night and its clear to me that theremismno way in hell 12 gauge wire will fit in those holes on the speaker board. Did you pull strands off until the wire fit in the hole?  

    I drilled the holes larger to fit the wire size.

    This sometimes removes most of the solder pad.  I clean off some of the copper PC board trace leading from the solder pad then bend the wire leads over and solder them to the exposed copper trace.

    Thanks for sharing that with us. Many times I've seen my Tech take the same approach.

    David S, First I want to say thanks for posting such an excellent article on your rebuild. Second, I'd like to ask for some help with my TA-N80ES rebuild. My amp more closely resembles your amp than my schematic that I have does. I have the two 22000uf 80v capacitors rather than the four shown on my schematic. I took the liberty of copying your Main Board (B) schematic as that is exactly how mine is. My question to you is that did you follow the polarity listed on that schematic, because the polarity marked on my schematic is much different than yours. Third, did you have any problems adding the extra two 22000uf 80v capacitors to your amp? Fourth, did you notice any significant improvement after adding the extra capacitors? The polarity question is very important as I don't want to blow up anything. Fifth, When you added the two extra capacitors to your amp, did you connect them positive to positive and negative to negative on each side? Sorry for all the questions, but I want to get this right the first time.

    Thank you in advance,
    Dan

    I did not replace the 2 large caps cemented into the large rectangular housing.  Those caps tested good & I liked the looks of the rectangular housing.

    Follow the information jehill posted in your Sony TA-N80ES Main Capacitor Help Needed thread.
