Micamold Capacitor Value and Type ???
#4

According to this website, TFB, you are correct.

But I wonder about 3000 pF in that circuit?

Very interesting. The primary of that IF transformer is slug tuned, as are many 1940-42 Philco IFs, and it uses that mica cap in parallel with the primary winding.

Being a Micamold cap, it's hard to say if it really is mica or not. Some Micamold caps have a paper cap encapsulated in that package that looks like a mica cap. The Micamolds are beginning to fail at a rising rate, also.

I would replace it with a new mica cap or an NP0 ceramic to avoid drift while in operation.
