old tube amp repair

greetings all, I have an old David Bogen D-25 amp that needs some refurbishing.
any good sites out there for parts, schematics, etc. the amp uses one 5Y3GT, two 6V6GT, and three 12AX7 tubes. its a small simple mono amp with switchable inputs for tuner, tape, aux, mic., high and low magnetic phone with one knob for volume and one each for bass and treble. I think it would be fun to have this working again and plan to use it as bass/keyboard practice amp among other things. any idea on the output watts??
once again thanks for any info.

For vintage stuff like your amp there is a site dedicated to old and vintage gear. You might want to ask the folks at www.audiokarma.org your question.:idea:
