Changed caps. It works well, but no amplification. When volume is low, it plays fine--increase volume--distortion. Hooked up extension speaker but more of the same. Used a signal generator at grid of 42 power tube, but same low volume. I assume it is this stage. Tried changing tube. I was thinking about removing the wires of the output transformer to give it an ohm check. Any ideas?
