Well, now, this is interesting.

I took a few minutes away from college studies just now and looked to see if I had the same Rider's schematic as you. Turns out I do; it's on Philco page 15-5 of Rider's Volume XV.

And it gets more interesting...

The Rider's schematic calls for a 350 pF cap while the Philco data calls for a 1.5 pF cap in this position!

Philco made some ceramic capacitors after the war that look similar to resistors.

If you haven't messed with it already...I would leave it alone, and look elsewhere for your problem. Those ceramics are usually very reliable.
