A few years ago, I found a Technics RS-616 cassette deck in pretty nice condition at a local thrift store. I think I paid $4.99 for it.
When I got it home, I found out why it was so cheap. I put in a cassette and the right VU needle pegged and the deck was making an awful electronic screeching sound in play mode. I figured it might be something to do with dirty contacts. Sure enough, on the circuit board there is the play/record switch assembly that needed cleaning.
I cleaned it along with all the pots, contacts, other switches, and it came to life.
I'm impressed with the quality of sound. It's not a top end Technics deck from that period, but good enough to make very listenable recordings.
The only other tweak required was to adjust the head, which is simple enough to do by ear and a known good source tape.
