Thanks JohnDoes it work with headphones??
If it does, the relay may have a bum set of points, or a cracked track under it, as Randy found on one a few months ago.
I would have to look, but the headphones may before the relay.
I would also suggest pushing tape monitor and speaker buttons in/out about twenty times. Dirty switches are quite common.
I didn't try headphones, actually I don't have any. However, at this point, both channels are working. I did replaced the speaker relay (as part of the re-furb) with a new Omron MY2-02 looked identical, but was wondering myself if the new one might be defective. Is it possible that even though the contacts are connected together inside of it, that one side might not be right ??? also, the solder joints are solid and the pads are not lifted.
I saw your suggestions in other threads about the Tape monitor or other dirty switches. I had already taken the front panel off (again) and re-sprayed all the pushbuttons with Deox and worked them in and out, so if one of them is the culprit I will probably need to disassemble the switch for a more thorough cleaning. I saw in another thread a guy showing how to remove the knob, pull back the spring to get the guts out. Have you ever tried that ???
