It’s small, think it’s 15w

Better too big than too small.

Then this one...100VA

Or this if you only need 200VA

AS-2T350 - 200VA 350V Tube Transformer - AnTek Products Corp (antekinc.com)

This one is in stock though.
Might at least pull the transformer covers off and see if it can be repaired or even partially hand wound to fix the break.

that, you will find, is a no go...

We got superglue…

And duct tape!

And an entire drawer full of hammers!

Was looking at those transformers today, not sure 350/0/350 is correct? I’m getting ~290vac from the good winding no load/diodes lifted. Won’t 350/350 be too spicy? The filament winding is 6.3vac and good. The schematic specifies 515vdc after the diodes...

So the schematic that was posted shows 515vdc at point A. If this is correct, then the transformer would be 515*0.707 = 364 vac (assuming no load). I think the 350/0/350 would be just fine as tubes will work over a wide spread. However that first cap is shown with a working voltage of just 350vdc - way too low if indeed the voltage after the diodes was/is 515vdc. That cap's working voltage is too low if the transformer puts out 290vac, which would give about 410vdc across that cap.

290 no load, my field of knowledge is more based toward mechanical engineering, I knew there must be math to fix this

It’s beveragè time though. I’ll tell yas a story of a cocksucker tried to pay me $10 for honing three cylinders and extracting three stainless bolts from an aluminum casting exposed to salt water another night.

Welded.
