"I would not use NFB from the output trans secondary but plate to plate fb from the kt to the driver tube."That kind of short loop NFB has a reputation for working best, when the driver is high impedance. The 6AC7 Octal pentode (gm = 9 mA./V.), with regulated g2 B+ and an unbypassed cathode bias resistor might meet your needs.
