Tboy make a good point. A Model T is basically a 5F6A front end, a Master Volume control and an Ultra-Linear power amp. There arent any examples of ultralinear power amps using 6V6s I can think of but Hammond makes several transformers in the 15 to 30 watt range that would work fine. Just decide if you want two or four 6V6s, pick an OT, then find a PT that will give a B+ in the 375 to 425 range. Use the Model T schematic as a guide.

i could just reduce the values of the power section but i feel it wont sound the same , thats why i'm looking at different power sections of different amps i'm looking for a power section that sounds very close if not the same to the model t.

It's not going to sound the same no matter what you do.

This transformer will get you pretty close:

Some of this guy's amps have ultra-linear outputs but no feedback. Schematics are hard to find.

You could try building one channel of a Dynaco ST-35. No Sunn enthusiast could find fault with that idea.  :-D
