A GS-35b has 0.12pF of anode-cathode feedback C. An 8877 has 0.10pF of it, so they have a fairly similar amount of internal feedback. Our 8877 low VHF-Q parasitic suppressor retrofit kit has both an anode suppressor and a cathode suppressor. It comes with a money back guarantee. So far, the only refund has been to a guy who said he did not know how to solder.
-- Today's trivia question: At its max freq of 1000MHz, what is the reactance in ohms of the output/input feedback path in a (g-g) GS-35b?

Very interesting. My guess: 1326
