    Back to my youth

    Hello everyone. I have just bought (close) to an old piece of my equipment I enjoyed back in the day when I was in the Air Force in the 70s. Just found a qrx 7001 sansui that appears to still function well. I had forgotten just how my 8001 really did sound.

    QRX Service question

    I recently scored a QRX 5001 because I am in love with Sansui Quad. My tech is very talented but we can't understand an issue that happens with one channel not playing at full volume.

    QRX-5500 120hz hum caused by my mistake

    While troubleshooting a dial lamp short that was blowing F1 fuse, I had a wire disconnected from the light box that has 6.3vac. (Lamp Power). When I was moving the light box around to get a better look, the loose wire accidentally contacted a wire on the 330ohm resistor that had 58vdc. See my...
