I just looked at the circuit diagram for those 6 off 470k resistors. Considering that the very nice Vishay resistors you've suggested are ~1p each, that looks like a very wise move; keep them coming

.

Re the VFO, is that a simple air-spaced cap that does the tuning? I notice that the digital readout dropped out a couple of times at certain specific locations in the tuning range, hence the Servisol comment. That's happened since its been in storage.
