3- With no stanby sw you send 329 volts ( for BJ) on a cold tube's cathode, automatic bias or fixed bias.

It actually goes to the plate/anode. The cathode is grounded and the grid is tied to the plate of the PI.
If the tube is not up to temperature, no voltage flows.
I do not believe in the "cathode stripping" idea. That is something that was never discussed in the 70s, 80s, and 90s.


TV, audio amplifiers... no consumer electronics in history other than guitar amplifiers and HAM radios have ever had standby switches.


1-Voltage never flow, current do.
2-Many, if not most, of these consumer electronics are solid state or if tubes they work on low voltage and / or low current . Not guitars tubes amps.
3- This do not mean stanby will not help; like I often wrote ; it is cost cutting.

I think we have gone around the question and we will not change our minds.
I'm off the topic.
Have a good day .
