Somehow the test ground point you are using isn't grounded to the negative or something. Tubes need hundreds of volts to operate. Can you show some pictures of the inside? And you say one channel does work?
Was wondering if anyone might be able to help im having issues out of one channel I dont get any sound. I checked solder joints they seem ok. So i did voltage checks of the tubes and seem to be getting strange figures. All measured to ground execpt pins 4 and 5 heaters which where measured to pin 9
Do you have your meter on DC - not AC?
0.xx voltages? And how are you mneasuring these?
