Hi and welcome,
I'd start w/ measuring the voltages around the 6L6 tubes. Pins 3,4, and 5 are key.  3 and 4 should be around +300vdc. Pin 5 abt -22vdc. The voltages you see on one tube you should see the same on the other.
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!
