Would anyone have any repair tips/schematics, etc., on a model
300350100 Mono cassette duplicator? Nothing obvious shorted inside,
and the electrolytic near the reed relay checks good also. Unit seems
well made otherwise. I have heard of other units having the same
symptom, so this could be a common problem of not recording copies of
cassettes. Thanks for any help!

when you say doesn't record, what exactly do you mean? does it move
when rec is pressed, does the switch activate the machine? ? is it a
mechanical or electronic problem?
in any case, check the connections in the rec amp circuits and bias
oscillator.
