Of all the hair-brained mistakes....when I broke down my Sony Cassette-corder WM-R2 to replace the belt, lo and behold, I have completely forgotten where a little plastic piece shaped a bit like a comma with a series of holes and a metal circlet goes. I am thinking it is a part of the record/play...fits around those buttons....woe is moi! Anyone have a schematic for it?

I bought it for 50 cents at a yard sale because I needed a small recorder. But I have found fixing it to be a very relaxing and addicting experience.............
