Carl 'burnt fingers' also weighed in with the snubber idea early on
(15 Mar 2013 11:35- see Page 3):

...I would try oscillation snubbers at the grid, screen and plate pins,
A 10-22 Ohm carbon right at the grid, a 100 Ohm at the screen with a .01
disc bypass right close to either side.

Thanks, Carl! I am definitely going to put a 100 ohm resistor right at the
screen pin (even though the LF parasitic was already fixed). I think that
radio already has a plate VHF parasitic suppressor, so I'll leave well
enough alone there.

I really don't use it very often. Need to get that VFO project finished. Just
need to complete its packaging. So many projects here...
