Hi there- I'm new to the forum and a neophyte in electronics..

I just recieved the Bogen c 100 c amp, and it's output is drastically reduced.. both mic inputs are at same level, but must turn the gain all the way up and 'eat' the mic for anything Close to a program level to output.. what could cause such a drastic drop in level, and what/how should I check?

might try cleaning the pots, and other connections first ...

like here -

try replacing the electrolytic caps in the power amp section and coupling caps in the preamp section. coupling caps and the feedback cap in the power amp section effect the overall gain of the system.
