Not sure what to suggest other than to turn the set on and measure those pins for voltage, where I'm sure you will find that B+ is present.

...and, make sure to bridge the M7 Relay to close.
Gad, what a twit I am sometimes.
The readings (resistance) are as follows:
V20 (6AC7) Hor. AFC: Pin 4, 696K vs 1.8Meg (spec)
Pin 6, 11.88K vs 20K (spec)
Pin 8, 24.9K vs 23K (spec)
V21 (6K6GT) Hor. Osc: Pin 3, 5.38K vs 6K (spec)
Pin 4, 8.7K vs 11K (spec)
Pin 6, 466 ohms vs 800 ohms (spec)
I'll get back to you with Voltage Readings. Pin 4 measurement on the 6AC7 seems odd...
