I have finished building my Crack amp only to find that there's no sound whatsoever (in either channel), not even any hum or static. Zero, as if the headphones were unplugged (they weren't).
I rechecked my soldering and everything appears to be fine. The tubes warm up and glow, I just get no sound.
Could a whole part be broken? I'm also thinking maybe there is some proper way to solder the rca jacks -- I put the wires in and made sure there was contact at the rim, then filled the hole with solder. Am I doing something wrong? What are the possible problems?
Thank you very much for your time and help.
