I found some of those ceramic tube caps in a Hallicrafters S-120, which I though may have been responsible for the low volume, so I tried replacing one, an audio coupling cap I think, took the old one, tested it in a resistance-capacitance bridge, and it was fine all thw way up to rated volatge. So apparently they were installing plastic film, or paper mylar caps inside that style of casing by the 1960s.
