Likewise here Rob.
For my friend's amp, before he decided to bite the bullet and buy a new
transformer, I had two toroidal transformers custom wound. Each had a HV
winding and the the other voltages were split over the two transformers.
The combined result being a much more substantial transformer, built for
50Hz operation. Another friend has a sheetmetal shop, so I had him
fabricate the box. The connectors were removed from the busted
transformer and so we had a plug in outboard transformer box ready to
rock and roll.
I still have the whole kit here. It will probably never get used as I'm
very unlikely to ever build a tetrode amp.

Yes EPD is a good outfit, I agree. Ten Tec made their own iron to
save money because they were cheap. They had a guy on the payroll who
did nothing but make their transformers but then he quit and went back
to where he came from (Canada?) not sure and I don't know what they
did after that. I heard they originally used Dahl iron but quit him
because he was too expensive. In those days I wanted the replacement
to fit in the box and I sent it to them and had the Dahl transformer
shipped to Sevierville. I think I paid Dahl 4 or 5 hundred dollars.
The Ten Tec service guy actually argued with me. They didn't want to
put in the Dahl transformer. He insisted there's was okay. After
two crap outs I wasn't a believer. I had to order them to use the
Dahl transformer. Nowadays I don't care if it fits or not. I'll put
anything that works outside in a box and run wire to and from the
cabinet to it like with other amps such as the L4B.
