Model 680 interstage transformer.

That's odd that you've got the proper resistance for the winding and it's not shorted to gnd as you wouldn't have the bias voltage on the 6A3 grids but it's not passing any audio. Mechanically it's like the core is missing!

Looks like the ticket.

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!
