How important are they and, by looking at the schematic, is there a way to tell what pins the 250mmf mica is conttected to on the 50L6GT? http://www.nostalgiaair.org/pagesbymodel...014176.pdf They can be pretty important, but I don't think the 250 at the 50L6 is your problem. But to answer your question you'd refer to a tube chart to figure out the pin #'s:

In this case it is between pin 8 (cathode) and pin 5 (grid 1).
A tube manual is pretty handy to have around, but here is an RCA manual that is a free download:
