The KBP-02 rectifier is an in-line package so you might find it easier to remove it completely for testing. I have a later Rotel RA 920AX amplifier which was originally fitted with the same rectifier. The amp blew two of them before I replaced it with a higher spec component. The KBP307 is a good bet as it has a similar flat profile and is readily available.

The substance at the base of the capacitors might just be a type of glue sometimes used for securing them in positon during manufacture. Anyway, let us know how you get on with testing the rectifier out of circuit.
