11v on the 6sq7 is a problem. Measure the resistance from p6 to the chassis should see a high resistance. Perhaps 50K or better. A wrong value resistor on pin 6 or + voltage on the grid of the 6SQ7 could cause this circumstance. Voltage on the 6SC7 are good the one you noted is .95v vs 1.2 not a big deal.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
