Hey guys, I have a small side project going on for this pre-amp. It's from either the 50s or 60s, everything works, but no sound comes out. Any ideas?
If no sound comes out, not everything's working! You need something to generate a steady signal, such as a sine wave in about the 1KHz range or so, and plug it into the input, then you need a silly scope to follow the signal, or backtrack from the output to find where the signal is stopped.
