I have an odd issue with a TEAC 40-4 unit that I've been working on for a while. It worked fine for a bit when I first got it, but then it started having this issue where the pinch roller solenoid stopped engaging the mech and the take up motor runs really slowly in playback mode. I tried replacing the motor run caps(and all the electrolytic caps) thinking that might solve it, but there's no difference now. If anyone has experience with this particular issue, I was wondering if you could help me out.
