You asked for an example ... I gave you one that repeated itself.
I am curious as to why I had to replace two 3-500z"s. The way the =
amplifier made a huge grunt and tripped the breaker ... with the =
3-500Z's shorting and pieces of either filament or grid being loose in =
the tube tells me something violent happened. And since it occurred =
while moving the top cover in relation to the tubes and tank circuit, =
leads me to believe it was an oscillation. What is your expert =
explanation please ?
>>I'd like to ask a few questions:
>>1.) What type of amplifier was it.
Henry 2K-4
>>2.) What type of tubes.
HELLO !!! Already stated.
>>3.) Why don't the photons generated in normal operation cause the=20

You asking me ?
>>4.) Why don't photons in gas-filled tubes specifically designed to=20

>>5.) Why do hundreds of other amplifiers without covers not fail?
??? Has nothing to do with what I stated.
>>6.) Since the saturated current of a 3-500Z is about 10 amperes or=20

I would really like to know what shattered mine.
>>7.) If the tube could supply that much current, how does it get that=20
>>current so fast through the high surge impedance of the path from=20

Good question ... but in this case as I recall there is no current =
limiting in the B+ or B- of the HV supply.

I have no explanation, only suspect.
