Philco 51-532
#1

I am working on a 51-532 and i am attempting to rebuild the IF xfmrs. I'm stuck on the 2nd IF. Can anyone tel me the correct values of the Pri and Sec micas. The online calculator tells me that the Pri mica should be 172pf and the Sec mica should be 120pf. I think these numbers are correct but what about the other mica caps that are attached to the bottom of the Sec tank? Are they there to bypass any remaining RF to ground? What value will work? Should the also be about 100pf?
Any suggestions will help.
