Take everything I say with a grain of salt as I am just learning about this stuff, however I can attest to the Tweed Princeton 5F2A as a wonderful guitar amp. A little more clean than a Tweed champ and a easy to dial in tone knob. I am biased towards the warm midrange woody sounds of the tweed amps versus the mid scooped blackface fenders.
I did consider that, but it would again prevent me from using existing components. The Ouput transformers for PP vs Single End are different and I would have to replace that.

I'm not saying that I WON'T do that, but I think I want to try some other things first. I f I go that route, I have the "two-stroke" plans from this book that I'll probably start with.

Maybe a similar dual triode tube that has a lower current draw? Any suggestions? It could really be any basing too, octal whatever.

The 5F2A circuit would be really easy to build in the chassis I have if I decide to strip everything out and start anew. I'll keep you posted. My pedal preamp kit should be here Friday, and I'm going to try a couple other variations of tone controls to see what combination works best.

I promise a video, complete with lousy guitar playing by yours truly when I get it dialed in.

I also picked up the wood for a cabinet. I think I'm going to add a cover plate, and wire cage to the chassis and build a cabinet for the 1X12 speaker with 1X12" Pine boards and 3/4" birch ply for the baffle and back. I'll get to that once I get the amp itself tweaked.
