Got it! :thmbsp:
Seller was really nice. Set it up and played music through AUX and tuner, everything sounded just fine. All switches work. No static with the volume knob. Tuner pulls in stations pretty well.
So... two things.
I got it home and took off the wooden casing. OMG. A thin fuzzy layer of dust over the entire circuit board! Definitely not going to power it up again until that is cleaned up. Any recommendations as to how to proceed? I'd hate to have to disassemble the thing. I'm thinking of using just a fine dry paint brush and a can of compressed air.
Next... that left channel meter is not working. Seller said it was working fine for years, then after he took the receiver out of storage to use recently, it wasn't moving. So... sitting idle, doing nothing. Maybe upon power up something happened? Is there a connector to check somewhere on the main board? If something has to be replaced, would it be some inner component or does the whole meter need to be swapped out?
