Servicing Yamaha TC520 Tape Deck
This Yamaha TV520 tape deck was brought to me with the complaint that the play does not work. As in practice, I opened the set and cleaned it thoroughly. Checked and found that the belt was loose. Replaced the two belts, one that of Counter and another that of RW/FF.
The capstan belt was loose too. As the size of the belt was not standard and I had no stock of it, I cut the belt and removed a small piece, and bonded it together using Superglue instant adhesive.
This was possible, as the belt was good otherwise.
Placed a wide rubber band on the two play wheels instead of tape and played the mechanism to check whether it was running properly. In this mechanism, if either of the wheels does not turn, it goes to auto stop mode. To thwart this only, I used this trick.
As the headphone socket was converted as a nest by that customer-friendly wasp, I cleaned it and checked recording without putting any cassette.
It was found ok.
Loaded cassette and checked play and another recording cassette and everything were found to be working very well.
Another job completed satisfactorily.
