Bill you're right about my desire to make this into a 200 watt amp and I'm willing to change the transformers from deceptecons to autobots to make it happen if it will indeed work. I have alread test fitted the 6550s on the chassis and its a tight squeeze but they fit.

I have a larger PT now 600watts 60hz 120vac that I harvested from an old Peavey Stereo Chorus 400. Would that be large enough to power four 6550s?

Also it seems like this am may already be designed to saturate the OT early since I'm getting power tube distortion with the master set to around 2 o'clock and the pre at noon. The amp cleans up tremendously as I turn the master down, but then I cant keep up with the rest of the band. I don't mind some growl but I wanna control that with my preamp setting...
Yes. The Band is way LOUD

Any ideas on where I can find an OT better suited for my needs?

Would there be a benifit in running 2 6550s over 4 el34's?
