    Sansui AU-999 secondary transformer resistances

    Dear experts, I need help knowing the resistances of the secondaries of a 999 transformer. After having obtained :banana:a multivoltage (heavy) :) transformer for my AU-999 100 VAC version to replace the (missing) original one, I would like to compare the secondaries with a good working unit, if...

    F-1159 driver board: KSA1220/KSC2690 vs KSA1381/KSC3503

    Hi all, I bought a pair of Ben's (peace, love and music) new blank F-1157 driver boards for my AU-999 project. It's all done except for TR811 and TR813. Ben suggests KSC3503 and KSA1381 respectively. I have a lot of KSC2690Y and KSA1220Y which I have used in the original F-1157 and seem to...

    AU-999 button needed

    I recently restored an AU-999 utilizing all the wonderful knowledge members here have on circuit mods and transistor substitutions. It came out outstanding. That said, the only short coming is the high filter toggle switch is missing the button. I can't really tell, but the shaft itself might be...

    AU-999 initial powerup, after restoration

    What is the best procedure to power up an AU-999 after a full rebuild? I've got a pair of 8ohm 100w resistors wired up on a board, and a dim bulb plug ready to go. New 1k & 5k trimmers are set to mid range: after reading thru the forum these are the steps I think I need to take: 1. Run the...

    AU-999 Overhaul Oddity on Preamp Boards

    I have gotten through the recommended recaps (well, electrolytics only) and started on the resistors. When I went to add the 1 meg resistor there was already a little 47pF cap in the exact location where the 1M resistor was supposed to go. Someone had long ago pulled the subsonics and crowbars...

    Sansui AU-999 recap and mod journey

    I had acquired this fine 999, which ultimately led me here to this forum for research, and it wasn’t before long that I became a Sansui fan. I always wanted to learn more about electronics and stereo repair, and it is quite serendipitous how this all happened. Not to long after that, I got a...

    fingerprints & drool x 30 years vs. Black Anodized Aluminum

    What's the best way to safely clean the black anodized aluminum surface of this lovely AU-6600 that I picked up recently? It absolutely shines, except for the fingerprints around the knobs. I have obviously tried warm water/soft cloth and even a bit of dish detergent. Nothing really takes it...

    Sansui AU-999 DC problems?

    Hey all! First of all, thanks for all the assistance. There's so many great resources here on these forums for this little amplifier. I've replaced all the electrolytics, and the usual problem transistors. I've even swapped some of the larger value resistors with new, Vishay metal film. I've...

    Revisiting the Sansui AU-999 - repair, rebuild and mods

    I've not been quiet about saying my honest feelings about the AU-999 in the past. My earlier Sansui experiences were along the lines of AU-666, AU-555A, AU-505, AU-222. I was already in love but when I got my hands on an AU-777 and AU-777A I really fell deeply. I knew I had to have the TOTL from...

    Sansui AU-999 phono input is extremely quiet. What's wrong?

    Hello, I picked up an AU-999 / TU-99 pair at an Estate Sale this summer. I've paired these with my existing Technics SL-1300 turntable, which worked fine with my previous receiver from the '90s. The Tuner sounds great. The auxiliary input sounds great from my an old iPod. The problem is that...

    The brute sitting between the two SP-6900X Sansui speakers. There is a near mint pair of Sansui SS-50 headphones resting on top.

    My Rig - Pic #1

    Since I'm in transition (between working and retirement) I'm living with my #2 son until Next April. So, I'm setup in the basement. This is my Sansui AU-999 and TU-999 with my Sansui SP-6900X speakers plus a JVC CD player.
