They typically look like a black dime with 2 leads coming off it.

Ive had about 10 GPR's apart and as of yet not 2 of them are the same.

The schematics shown by MB do not show any of the electrolytic capacitors which are a highly suspect common failure item. When replacing them, make sure the new capacitor has the same or higher voltage rating.

Radio shack still has them or many many sellers of them on ebay. Just remember when buying from Asia you
will have a roughly 10/15 day delivery. Much cheeper from Asia.
