I worked on this some more today.
So far I've swapped tubes in the amp section; removed, tested, and replaced the output transformer (checked impedance with a meter, applied voltage to the secondarys/metered primary - tested fine all times); double checked all connections; tested speakers - working;
The only time I get any sort of noise through the speakers is when I tested the high voltage on pin 5 of the 6V6 sockets (tubes installed), I would get static through the speakers, and when I removed a 6V6 with the organ on I would get slight static through the speakers.
Any other tube amp I have, if I remove a power tube or the phase inverter tube, I get a loud pop through the speakers. This organ does not do that. I just get a little static if I remove a power tube, and nothing if I remove the PI.
Everything powers up fine, I get good voltages on the tubes which tells me the rectifier tube is functioning properly, I just get absolutely no sound at all. It worked when I picked it up, and all I did was remove the 26-1 kit and plugged the speaker/power connector right back in.....???
