Echophone model s3 no sound
#4

How much - voltage do you have from the ct of the hv winding to the chassis? Need abt -50v. With -1.7v on the grid of the 45 the plate current is going to be pretty high. Disconnect one end of the C-5 and see with the - voltage increases. If C-5 is leaky that will apply + voltage to the grid of the 45, not good.

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!
