Model 680 interstage transformer.
#2

Hi Va.
Looks like pri is 475 ohms sec is 1k ohms g to g. Interesting I checked to see if the bias was too high at -63v but that about right  Just for grins you can put a cap for the plate side to one of the grids. Tipically the secondary will go open and you'll loose bias one one or both output tubes.

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!
