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.

I know. I'm getting a full raster.
I checked T3, the Horizontal Output Transformer, just for kicks. It read the following:
Pole 1 to 3: 407 Ohms, Spec 405
Pole 1 to 2: 168 Ohms, Spec 165
Pole 4 to 6: 7.3 Ohms
Pole 4 to 5: 7.1 Ohms
Pole 5 to 6: 0.5 ohms (this is the Width Adjustment)
So, that looks ok to me.
I'll do voltage checks, and get back to you...
