I just got a 1967 Ampex 440 4 Track Recorder and it has one problem that I can't figure out. When I press the play button or any other button on the control panel it the does the same thing. The rewind motor goes into rewind mode and the take up reel goes into fast forward mode. So, it is running in rewind and fast forward at the same time. Again, it doesn't matter which button you push it always does this. Anyone have any suggestions on how to fix this?
