What a thread! Lol

Depending on who is playing, that might be the more preferred option....My problem with the standby switch has always been “turn on the standby switch after warming up”. To me when you turn on standby you are switching it to where you get no sound while mains is still on.
This is my understanding as well. Admittedly when I was getting my electrical engineering degree tubes were already considered ancient technology and I didn't encounter a single word about them in my formal education, but that's also what I see when I look at old Fender schematics. In my opinion it would be "best" to just leave the Standby switch in the ON position all of the time, hard-wire it there, and yet I do find myself still using it for beer breaks occasionally! Old habits die hard.I said backwards because the standby does not limit the inrush current to the plates and power supply capacitors.
With the standby open, the tube rectifier is allowed to warm up and deliver full voltage, then you flip the standby and blast the caps and plates with full voltage.
Leaving the standby switch closed, the tube rectifier gradually increases voltage to the filter caps and plates as it warms up.
Under no circumstances does the standby switch limit the inrush current to the power supply or tubes.
When shutting off, all opening the standby switch does is disconnect the rectifier from the filter caps and plates. The caps are still charged (and will remain so for some time).
It doesn't hurt anything to hit the standby before shutdown, but there's no benefit.
I would say that it depends on design (to be on the safe side as there are many different amp manufacturers), but if you're talking about old Fender type circuits, the expert consensus seems to be that they are unnecessary and potentially damaging or shortening tube life over the long run.So what’s the final consensus….?
is using the stand by switch bad or good???
For my amps with no standby switches I just hit the building breakers between sets. This also makes it clear when our break is over as the building power comes back on ;-)Now I'm upset. I don't have standby switches on my pair of amps in my gigging rig. Does this mean I can't grab a beer in between sets? Should I tuck dollar bills into my cathode's g-strings and ask them NOT to strip?
I know....I'm going to install standby switches!
You are just thinking creatively...I do know what you mean...amazingly enough,My problem with the standby switch has always been “turn on the standby switch after warming up”. To me when you turn on standby you are switching it to where you get no sound while mains is still on. So when you are powering amp on you’re already in standby and therefore to play you switch standby off.
So when you are playing your standby is off, right?
I don’t know why the concept is so difficult for me to get lol. Just the way it’s worded is confusing to me. Anybody else think this way?
