This is what I refered to in post #6

And to check the resistance on the transformer secondaries, check the resistance between 5 & 6 and compare it to 7 & 8, they should read close to the same resistance

Points 10&5 and 9&6 are the same, I just picked a number.
So one of the secondaries is open, now you need to find a transformer.

Aha, guess I'll start hunting for one. Thanks.

This might be what you need, I have no idea who they are. Figured it would be a challenge to find a reasonable powerboard or transformer, ran across this, you may find a better price: https://www.yoycart.com/Product/544313881164/

Check the numbers on your transformer, see if they match up.

Hm, the part number doesn't match up.
I'll tear down the transformer anyway and see if I can purchase same gauge transformer copper wire and redo the second winding.

What are all the numbers on your transformer?

Maybe, here's a guy building one: https://www.youtube.com/watch?v=ZzKUQkAnvrA
