Ok, I refurbished this M90 a couple of years ago and it's been sitting, nicely wrapped up, since.
I usually verify everything is working before calling a refurbishment done so I'm fairly sure the recording function was working before I stored it away.
I recently pulled it out and was checking a remote I have for it and tried the recording function and noticed the left VU meter was just holding steadily in the red/orange and it didn't matter if I was in manual (any volume) or automatic mode.
I just tried recording on a tape and sure enough, the left channel has a constant feedback noise and didn't capture my voice at all, the right side works fine.
It plays tapes fine.
I don't really have time to rip into this and troubleshoot it right now so I figured I'd see if anybody has any ideas.
I'm fairly sure I've had this problem before but can't remember which box it was or how I remedied it.
