Hi John and Welcome!
I like to take the simple approach. Would use an ohm meter to find the ct on the secondary. Double check that it's going back to the volume control. Be sure that you have a good ground connection at the speaker. The two ends of the secondary aren't critical, if they are reversed it can cause the oscillation problem you are having.
Good luck w/it

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.

Now I think I've got!
