Nonsense.
The "stray" inductance introduced by the wire from the anode to the blocking
cap, from the blocking cap to the tune cap and the internal lead length inside
the tune cap, and the return through the chassis back to the tube are ABSOLUTELY
ESSENTIAL. to creating the VHF resonant circuit in the first place. The
parasitic suppressor is not "before" this LC circuit, it is right in the middle
of it.
Those are all "strays" and to say they have "minimal effect" on a parasitic is
ridiculous.
