I have seen very nice looking 2235B in local thrift for 40$ - but upon quick testing through headphones, it obviously has some serious issues. Regardless of the position on balance slider, both channels are always playing - in fact it seems like one channel playing in mono on both sides.
When I press Mono switch and with balance slider in the middle, there is no sound (?). Once I move it to extreme left or right both sides playing again, in mono. DC offset on left side was 5mV the right one is +500mV so something is obviously wrong there. I could not open it but the vinyl cover over one part of heat sink has peeled off and it looks like extensive heat. I would bite on it for this price, but symptoms are a bit weird and looks like someone was monkeying inside. What bothers me even more is that protection does not kick in with all that DC on the right channel. Any thoughts?
