REPLY:
You are missing the fundamental purpose of a parasitic suppressor. It does not
"trap", "load" or "absorb" the parasitic. Instead, its job is to reduce the
gain at the parasitic frequency enough so the tube will not oscillate.
It is all a matter of gain. Not "loading", "trapping" or "absorbing" the
parasitic. If the parasitic suppressor does its job of reducing gain correctly,
there won't be any parasitic oscillation present to be "laded", "trapped" or
"absorbed".
