Rich, you are avoiding answering the issue directly. The question was:
Does the spark that is created by hotswitching the input relay have enough
amplitude to create a sufficient signal at the input of to create any
sufficient ringing at the anode (output) of the tube?
That's what I ask. You claim that the spark created by hotswitching can cause
anode ringing which can be a seed voltage for parasitic oscillations. I don't
dispute the ringing. My question is can you prove that that ringning created
by the spark is of any kind of a sufficient amplitude??
I'll use your hammer and bell analogy. If I very lightly tap the bell, the
ringing will hardly be audible. If I hit the bell with full force, the ringing
will be very loud. The spark is the hammer. The tube the bell.
How hard is the hammer hitting the bell?
