I just picked up an Otari MX5050 1/4" half track machine. The problem is no signal passes at all on the RIGHT channel. Nothing in and nothing out. Also when I press the Test OSC button, it only generates a signal tone on the LEFT channel, and only the LEFT VU meter moves, no movement on the RIGHT VU meter.
What could be some of the causes? I'm not a tech, but I have some ability to be a home techy. Trying to determine if I can fix this with some cleaning or mild soldering? Or if it needs to go to the shop.
TIA
