How about one for actual AB1 or AB2 operation? The spec that mentions
the mfgrs recomended values for typical guitar/audio amplifier operation.

: It is typically quoted as 2000 volts (or more) for both
: the EL34 and the 6L6GC.

In AB1 or AB1 amplifier operation..? Where's the link to that data sheet
Phil?

: Very high peak plate voltages *are* experienced in a guitar amp.

ZZZZZZZZZZZzzzzzzzzzzzzzzz.....!!!! Oh, you put us to sleep Phil. Since
you're having so much fun. We can all say that "very high peak plate
voltages *are* experienced in most amplifiers. Oh joy, now we all have
some really technical information... but not from you Phil.

: In a Marshall it can reach *5000* volts peak during overdrive !

No where in the original post was a Marshall Amplifier mentioned Phil.
Talk about going off topic again.

: In a Music Man it cannot exceed 1500 volts or double the plate supply.
: That is what those HV plate diodes do.

So figure some bitter AH like yourself puts an untested low dollar
replacement tube into an amplifier with higher plate voltage. Regardless
of the amplifier model (just for you Phil) a tube "glitch event" is not
good news. Do you put untested tubes in amplifiers Phil?

: ** Output tubes operate at well over 1000 volts peak in the majority of
: guitar amplifiers.
: In a Marshall, or similar amp, peak plate voltage can reach +/- 5000.
: Data sheets for the EL34 give the *plate max voltage* as 2000 volts.

How about any mfgrs data sheet for actual AB1 or AB2 audio amplifier
service using the 6L6GC? What's that value you seem to never provide?

: The max **plate supply** is given as 800 volts.
: Which has NOTHING to do with "hi=pot" testing.

High-Pot or Hi-Pot is related to testing tubes (& parts) for
breakdown at higher potentials. You drone on about it being bad
news to place tested tubes into amplifiers. I guess you're going
to overtake Groove Tubes, NDB Electronics or New Sensor as the
better tube re-seller very soon. If you're placing untested tubes
into amplifiers with just the word of the tube seller, you're
just another bad hack Phil. And a bitter one at that...
