I own a Sony TC-WE475 stereo cassette deck I bought for 25$ about 5 years ago. Last year, the playback side (left side facing the unit) started to sound weird, like the playing speed was suddenly too slow. Recording side (right side) plays correctly, though, but I plan to copy several cassettes soon and I'll need both sides to work well to make copies. What fixing cost should I expect? Is this unit worth that fixing cost? I don't know a lot about cassette decks, I don't want to get ripped off of 60$ if it is a 25$ fix. I'd fix it myself if possible. I hate to send good stuff to the junkyard, and I wouldn't mind to pay 30 or 40 dollars to have it fix.
