Bogen RP-150BM

[Jdownj]

I just won an eBay auction for a Bogen RP-150BM. I was looking for a project, and(happily) won the auction for a low price without doing a whole lot of research. It has issues, and is missing parts(top of enclosure, etc) but appears to be complete electrically. This is a mono unit, AM/FM receiver and PA amp. The seller describes one of the EL84 finals as getting "too hot", probably red-plates and burned up.

Does anybody know how/where to get any service data on this? I see that radioera.com has a service manual for $25, is that my best bet, or is there another place I should be looking?
