On second thought you could just drop in a 50c5 in place of the 35c5 that would bring the string up to 121v reducing the load on the varistor. Philco must have had a gut of 35c5's in '53. Most of the time you won't find in an AA5. Typically they where used in sets that used 6 tubes like a AC/DC set with a RF stage or a AM/FM set. The engineers at Philco must come up with this scheme to use up some overstocked tubes.

figure out what all those squiggly meant.
