The way Philco does it is the caps are put in parallel to the primary of the interstage or output transformer, adding the next cap in parallel to the previous one. A bit of a brute force approach, I agree. The pot regulator should be in the grid circuit, not plate.

Anyway, I have rebuilt the regulator. Same thing as in 90 or 111, just no backelite box.
