The 6k6 draws less current than the 6v6 so I wouldn't think that it would be the cause of the open fc. Maybe a shorted 2nd filter cap, wire rot, or something else down the line. Be careful w/an open fc there is no load on the hv supply so the voltage @ the 1st filter is going to be quite high and could cause it to short then the rectifier tube then the power transformer.

I was down in the basement in my dad's

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
