So I just re-capped Equalizer, Tone, Driver and Power boards in my 881 and thought all was well until I just realized that when listening to records, the left channel is devoid of bass frequency content. I've ran both turntable outputs into the 881's R phono input and they both sound normal there, so it's definitely isolated to the L phono input. The FM and AUX inputs seem to be fine on both channels. So would troubleshooting need to begin with back of the L phono RCA jack? Anything specific come to mind that I should take a look at, on any particular boards? I think that I can follow the 881 schematic to trace the signal from the input but I'm no pro at doing so.
Thanks so much for you input!
