Hi Dick,
My acid test for IF transformers is do the trimmer peak when align. If not I'll dig in and see what's going on. Think I remember Ron posting that those two caps 100mmfd are built into the ceramic so they are unserviceable. In terms of values it not very critical they are used as a rf filter as apposed to being part of the tuned circuit.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!

Terry
