In Reply to: RE: Onkyo A2090 cassette deck posted by Michael Samra on April 29, 2017 at 13:10:51
When it plays ok it sounds good but when it doesn't, the LEDs do drop out on the left channel.
The grease in these old decks gets dried up, experiencing the same issue with an old Kenwood unit. The slide for the head assembly is dragging causing the head to have poor contact with the tape, the deck needs servicing.
If he can't service it himself, it is unlikely that he would be able to recoup the money for service in the resale value. Cassette decks just are not worth that much. I wish it were otherwise. I have a stack of Nakamichi decks ...
I'm wondering myself if I ever get my money back that I spent on the restoration and recapping project on my Revox/Studer B215 cassette deck. But nevertheless, it sounded even better now than when it was new.
If a thing's worth doing, it's worth doing well
This is a very sophisticated deck. It also has repeat play but when it cuts out,take a handle end of a screwdriver or wooden or plastic stick and start tapping on the relays.You can test the record and playback amps by putting a signal into it from a stereo tuner or any source and see if the signal meter drops out and do this in record with the pause on. Also,take out your tapes and see if there is any chewing on the outer edge as this would indicate mechanical issues,

I believe I resolved the problem with the deck. I did clean everything but the main problem that I found --as you suggested--I started tapping on some components and found it was one of the 4 circuit boards loose. Once I reset them it has been working great.
Thanks to you and all who sent me suggestions.
