For what it's worth, they're described as "ceramic" in the Rider's parts list, although I guess that could mean garbage paper dielectric inside a ceramic tube.

All (14!) of them occur in the audio & video IF sections, where they are used for bypass, AGC filtering, and decoupling, according to Sams. Examples: C6/C8, C10/C11, and C13/C14 in this schematic snip:

I'm usually loath to replace a dozen of anything in the video IF, because . . . alignment.

I think you'd better leave them alone. Even if they're paper types, the leakage should be insignificant with such small values.

That may be the case with Russian made paper caps, but American made paper caps (and many Japanese caps) are crap...I've seen plenty of papers in that value range nearly dead shorted or leaking heavily even below 50V.
