My guess is that your measurements are consistent with a non-connected
toroid lead: one of the stages may be loading down the other because it's
not resonant.

I'd be surprised if it's something else, partly because every single Sierra
I've personally fixed had nothing but munged toroid leads! I'm revising
the toroid winding instructions in self-defense :)

If you have to replace caps, start with the coupling cap between resonant
sections. Much less likely that anything is wrong with the trimmers.

Good luck, and let me know what you find.
