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.
