I've been scratch building a tube amp and I have finally finished wiring it up. I put it on the variac and cranked up the power - no smoke! Unfortunately also no sound. Not a snap crackle or pop out of it. I have an OPT that is supposedly from a Fisher chassis. I ohmed it out and it should be fine but I want to make sure that I have the wiring right - so does anyone know what Fisher used for their color codes?
