Thanks for the impressive and detailed work.
Doubly so for the driver transformer analysis and dissection, usually very hard to find info.
If anything, because often not even the original manufacturer had any clue about them, just ordered specs to be met and supplier filled in with their expertise, providing a finished part, ready to use; amp manufacturer didn´t need to know, or care, about wire diameter, winding, interleaving, core magnetic properties, etc, just that it met specs .... and at a reasonable price, of course.

That's insane man! Don't do it!

Ha, just kidding, cool idea, have fun.

I've done something similar in running the Thomas Vox solid state preamps into tube power amps for troubleshooting/testing.

One of my "someday" projects is to get one of those Vox ss preamps and use it with some Bogen tube power amps I have which are very similar to the fabled 7- series English hybrid Vox amps.

My own quasi- 7 series.
