Continued replacing caps. I've pretty much cleared up the FM issue. Check this out: it was actually the coupling cap between the volume control and the 7B6, which has virtually no voltage on it, plus the bass and treble caps, which really have no voltage on them at all. Almost finished with cap replacement, then I'll check high value resistors that have a tendency to drift to twice or more of their rated values.
The FM on this set, now that it's stabilized (doesn't even have too bad of a drift problem!) turns out to be really quite sensitive, better than many of my more modern sets.
