The voltages tested were between the tube pins and chassis and were all +-10V from the 38-10 schematic. I do get a hum at high volume and when touching the cap on the 6q7. Just can not get any audio without changing the tube out. Gets kind of expensive to replace a tube every couple weeks. Everything I put in a new 6v6, I get great audio for a week or two depending on usage. Then I get no audio except the humming and the 6v6 will test bad. All of the other components appear to be originals with the exception of the caps I replaced as well as the power cord.
