Swan 700 tune the VFO amplifier plate circuit using high impedance telescope input see wave realtime

SO from the VFO amp the output goes thro two capacitors before getting into the GRID
of the 12BE6 mixer. I think this was a REASONABLE way to PEAK the plate circuits in the
VFO Tank circuits.
Seems the circuits were was out of adjustment for peak power and resonance as feeding the mixers.
Checkout how the amplitude of the wave rose on all the bands,
