>I checked the continuity on the Oscillator pin 4-6 and unfortunately there is not continuity!!!
So the next step to do would be to measure the resistance from pins 4 to 5 then 5 to 3 then 3 to 6. All should measure a near dead short. This will determine which section has the fault. If you are lucky the winding will be one layer wound flat onto the form so spotting the problem will be easier than if it was several layers on top of one another. Also the SW winding is somewhat smaller (less turns) than the the bc band. The bc band would be around 90 turns and your sw band would be about 30 turns.
The faults would be a break the wire or a green dot indicating rot.
Happy Hunting!

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.
