This Sony Tape Recorder Model TC-520CS was brought to me by one of my best friends, for changing belts. As you can see from the second photograph above, he had sealed all the screw holes with cotton to prevent wasp building its nest.

But you just see how smart this insect is. She has built it inside the battery compartment, which fell off when I opened the lid!




How did it manage to sneak into there is something that defeats me!

Anyhow, after my appreciation and grin over the joke as to how it outsmarted by friend, I opened the set, which was not having much dust and dirt inside, and cleaned it up as a routine. In order to access the mechanism, we need to remove the front panel, unscrew the mechanism holding screws and lift it up.




The belts can be replaced only after removing the capstan holding bracket. I replaced the belts and fixed it back. Gave power and tried, it worked very well.

So, fit the covers back and tried it again, playing one full cassette (A and B side).

Delivered the set back to my friend myself, on my way to the hospital, whistling and beaming with the satisfaction of having added one more to the bulging bag!

    Nature tries to gain its territory back, but apparently mostly in countries like in yours Parasuraman. Like the often found lizards. These things never seem to happen very often in my country. I assume you didn't glue the belts this time, as you found new ones for this Sony cassette recorder.

      Yes, you are right. (1) We have wasps building its nest in screw holes and that is really a pain for technicians, as screw driver cannot have a grip on the head of the screw. We have to do a lot of cleaning including spray to remove this! (2) There was no need for gluing, as I had the exact replacement with me. I have more than 300 to 400 belts of different sizes!

        Hello Sir, this is the nightmare of all antique collectors. We have wasp, lizards, ants nesting inside the tape. I also have my collection spoiled this way. I have 2 National RQ-2157 tape recorder which are damaged now. The belts are broken n i cannot find a replacement. Sir, do you have a replacement rubber belt for National RQ-2157 tape recorder ? I would like to purchase if you have. Thank you.
