    Sansui 7070 Tuner Board (F-2614) Missing RFTransformer

    I'm bringing a clean 7070 back to life and am getting close to firing it up - just waiting on the new output transistors and some fuses to arrive - but I've run into a possible issue with the tuner board (F-2614). One of the FM discriminator transformers appears to be missing - T03. The...

    Sansui AU-3900 vs AU 217 vs 6060, what’s better?

    Hey guys! I recently purchased a Sansui AU-3900 and honestly for a solid state it surprised me how tube-like it is, however one of the transistors is messed up so it’s giving me static, crackle, and pops from the right channel. I spoke to the guy and he offered me to exchange it for the AU 217...

    Sansui AU-6900 Posistor destroyed

    Re-assembled my Sansui AU-6900 and forgot to re-attach posistor to heatsink. Turned on amp and it blew 2 fuses straight away. 1. Could not attaching posistor be the cause of blown fuses? 2. I also need to find a replacement posistor as I've accidentally destroyed mine in meantime (don't ask)...

    Hi all! I have fun tinkering with all sorts of things and have recently been putting that attention on building out a vintage audio set-up.

    Sansui QRX-3000 Driver Transistors

    I just finished repairing a QRX-3000 that had both front channels out - 2 outputs (2SD313), the output caps and the NPN drivers TR805 & TR806 (the schematic calls for 2SC634As but the original parts that were installed were 2SC1364s). Everything else tested good. I used 2SC1060s for the...

    AU-911DG and an EQ (Lokius) - Pop Sound when turning ON/OFF and Tape/Source change

    Hi everyone, I use my somewhat recently acquired Sansui AU 911 DG which I truly love for the sound, but recently I introduced an EQ on my system, a Schiit Lokius, and found that when I turn the system on, there is always a pop sound if the volume is around level 35, and the louder the more...

I have read so many good things about both, especially the AU-777 series. I am currently using a higher end mac stack (MX110z / mc2505) but...
