Switchable output transformers? Is it possible?

[VintageCharlie]

Dear forum members,

i'm thinking about a true JTM-45/JMP-50 hybrid. It seems like the OT has to be one of the biggest differences tonewise between those amps.
So i was thinking if it is possible to give it a JTM-45 AND a JMP-50 OT that can be switched, then change tubes and rebias. Or would a custom wound OT be a better option - one that has a tap for el34 and one for KT66 or 6L6GC (3.4 and 6.6, if i remember correctly) - and then install a switch to go between both taps? I know a tech who winds his own transformers so maybe he could do this?
What is your take on this - try it or leave it?
I know - some will say - just get both. But it's too expensive and to my ears there is also too much similarities tonewise to have two seperate amps for this.

Best regards,

Would be much more practical to get a custom wound OT with a multi-tap primary for the different tube types and switch between them.
