Ok so thing are looking good around the output stage. The 44 1st audio looks like it sez 4.2v on the plate. Kinda low. Have a look @ 57-60 to see those are in tolerance. One down here wound make both the plate and sg voltages low. And #62 &64 would just effect the plate voltage. Once this is sorted you should able to touch the cap on the 44 and the speaker should buzz like crazy.
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!
