Help Please! 38-116 Troubles
#8

What I was thinking was that the driver transformer was open. Seems the be OK. Do you have -25 on pin 5 of both 6L6's?
111 maybe your problem with the 6R7 circuit. 111 controls the grid bias for that tube. Without that resistor the bias volt is going to be too high.
If you touch the grid cap in should make a loud buzz in the speaker. Does it?

When my pals were reading comic books
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.
Circa 1966
Now I think I've got!
