I posted at the Sansui forum, but I probably should have posted here first as this is not a problem unique to Sansui. Anyway, here's my situation: I just scored my second AU-9500. I was foolish enough to let the first one go. I'm determined not to repeat the mistake!
I get it home, hook it up and I get VERY loud trash out of the left channel, static like noise. It reminds me of what you get if you pull an RCA jack out of an active in put, but much worse.
I disconnect the left speaker.
The right channel is fine. I adjust the volume and all other pots and switches and there is no static at all. Doesn't look like a quick fix for deoxit. As you can imagine, I was immediately bummed out.
So I tried the left channel with A, B, C and headphones. Nothing but extremely loud static with the volume all the way down. That's right, the volume is all the way down, but the noise in the left channel sounds like it's all the way up.
Next, I pulled the Pre-Out Main-In jumpers out. Hooked my computer into the main in and just used the amplifier section, completely bypassing the pre amp. Slowly turned the volume up on the computer and played a song off iTunes. Both channels are nice and clear.
The issue, I figure, must be in the pre amp section. The amplifier is fine. I put the jumpers back in and hook everything back up and test it. As soon as I hear the relay click, the super loud garbage comes out of the left channel.
Anyone out there have an idea of what's going on here?
