I'll have to do a little more investigating when I get the chassis (it was shipped today) with regard to the driver transformer. All I can do is try it, if it works, great. If not, well then I'll go with the transformer Terry recommended.
In the meantime, I found a power transformer I had on hand that would work to try...it’s not the same shape or size so wouldn’t look right. In doing so, I found I have another problem with the radio...the filament circuit is grounded! Somewhere something is touching and that’s causing a draw. The transformer I'm testing with is fine...no leakage, so I know the problem is definitely when I connect the filament circuit. That's when the draw appears, even with no tubes in the chassis. I guess there’s some serious wire tracing in order!
