Thanks for the great suggestions Eli. I had been assuming SE, as PP requires 2x the tubes and around 2x the current. I really appreciate you researching the OP tubes and rectifiers. I used the Edcor CSXE series on another amp, but I believe a lower impedance.
The transformer is indeed potted, chokes as well. It has a "Spec" number (14513) but I don't know if they are military or not. They are black, and the PT weighs 14 lbs, 6 oz. I didn't mention before that the 5v filament windings are each rated for 3A. One of the 6.3v windings is rated at 2A and the other 2.5A.
Still quite a few options out there, but hard to anticipate what the PS would do near its limits.

The KT66 draws 1.3 A. of heater current, while the 6L6GC draws 900 mA. of heater current. Also, the 6L6GC can safely dissipate a bit more power.

Seems like the 6L6GC is the O/P tube to use. Jim McShane shows a "reissue" black plate TungSol 6L6GC-STR for $21.50/tube. Yum!
With some 'A2 action, 12 WPC is not an unreasonable target.
