I know there are other threads with the same general theme, but I believe I need some deeper help. I rebuilt a friend's EP-3: New electrolytics, drive belt, tape, felt, general (and thorough) cleaning, degaussing, etc. The unit sounds great overall, but I cannot get it to go into "run away" oscillation. Bias level, rough azimuth, record level, and bias trap all seem to be correctly adjusted. Any ideas? Your help is appreciated!
