Your next step is to prove out that the preamp section has its needed voltage to run on, that being the + and - 8 volts as seen on the schematic.
This amp is a real PIA to work on with everything mounted to that one front board so take your time when making readings.
What I do with my hot meter probe is tape the metal shank up so only the very small tip is exposed.
