    Beginning my Sansui AU-919 restoration

    I restored a Sansui AU-717 last year for another AK'r and was very impressed with the sound quality of the finished unit. I documented this restoration in the thread below: https://audiokarma.org/forums/index.php?threads/sansui-au-717-restoration-experience.1080560/ In April of last year I...

    Sansui AU-919 Restoration

    A few months ago, @Vintagear pinged me, regarding an AU-919 on CL that looked amazing in the pictures. He knew I’d been looking for a good condition 919 for a long time. We immediately sped to the seller’s location. I drove and @Vintagear held on for dear life. LOL. The seller was an older...

    Hey everyone, i just bought a Sansui AU-919 on craigslist and in need of some help. The guy said it was fully serviced, but I'm not sure if he is telling the truth. Can someone here spot if the Black Flags exist in this unit (see attached photos)? Any help would be appreciated

    AU-D907 for restoration

    This is my latest on the bench for restoration, it has a few problems - just the normal stuff that's pretty much expected with a unit of this age. It's new owner tried it out and found that one channel was not sounding good. The technician who had it first corrected a protection issue, but...

    A curious anomaly - 07-series amps without power outlets

    My AU-719 has no power outlets on the rear. I only noticed it when I went to plug in a TU-719. A quick google image search turned up one other, in Denmark. Today I came across a pic of a 919 with no power outlets on the rear. It was also in Denmark.Coincidence ? They don't appear to be...

    Yep, it's that time. Finally got a little bench time to start on the one recap job I've been eagerly anticipating for awhile. :banana: Note this thread will be a long term thread, as stuff comes in I'll have to set this aside from time to time. Original thread on how I got it is here...

    Rare reed relay substitution ( a visual how to )

    In the past here on AK I've asked about possible substitutions for this Hitachi 24V reed relay . Although there were a couple of what I am sure were good suggestions, there was nothing easily get-able for me until I saw this today. Well it seem some good chap here in Japan who goes by the...

    Cambridge CXN into Sansui AU-919

    Having worked hard and saved hard over the years, I decided to treat myself to a Cambridge Audio CXN network player, received yesterday. I like the CXN very much, other than its sound level via my Sansui AU-919 amplifier being too high. At normal (not soft, not loud) listening level the amp's...

    Another AU-919

    Yesterday I had the pleasure of meeting another UK AK member Multimode (David) - he delivered his cherished AU-919 to me for reconditioning. It is a very clean example, at least 9½ out of 10 for cosmetics, and completely untouched on the inside. The icing on the cake is - original output...

    Recommendations on professional restoration of an AU-919

    Hello. I live in Norman OK and recently found a super clean bone stock AU-919. I was thrilled and absolutely love the sound. I'm not an experienced listener but of the 4 other amps I have around it sounds the best hands down. It runs cool and has zero issues. I like it better than a friends 9090...

    Sansui Blues - 5000A and AU-919

    OK guys, I'm just a parts changer. I'm a very careful parts changer. I read up all I can, make extensive lists, maps if you will, to the completion of recapping and up dating of transistors and I go in with the idea that I'll do no harm. Most times I hit the mark and I get a working receiver...

    AU-919 FET problems

    I have a Sansui AU-919 that goes into protection mode so I asked Northridge Electronics to take a look. Here is the response: Your right channel power amp intermittently produces DC at the output and that's why the protection is not turning on. I suspect the problem is the dual differential FET...

    good advice

    I have taken on one of my biggest projects ever, a blown Sansui AU-919. I have cleaned it up, replaced all the electrolytics and black flag caps and the output transistors with 2sa2223A and 2sc6145A. There was only one obvious thing wrong with the amp upon tear-down: one of the emmitter...
