#1 is silly. But I would also not plug/unplug without the amp in standby, don't like the loud pops
On #2 it's surprising how stable some electrical things can be over time when they're not disturbed. I would imagine issues come from living things going in there that shouldn't, causing nightmares
THANK YOU SO MUCH, cryptkeeper

When they warm up for a few minutes
The bloom comes back
Of course it could be my playing is stiff and sterileEHD

Now the interesting thing is that if you have a tube rectifier, the voltage naturally ramps up as the rectifier has to warm up as well. On a solid state rectified amp, it is more instantaneous.
Correct me if I’m wrong, but when you dig into the history, everyone keeps including them because that’s how the previous amps did it, right?

Well for number 1, as others have said it’s a misunderstanding of needing to have a load connected when powered on.
For number two, as caps and tubes age, the chances of them “popping” is statistically more likely when it’s powered up than when it’s not, right? It’s not surprising that the inrush of current may cause failure, but what are you going to do? Unless the working theory is that amplifiers that are used daily are less likely to fail catastrophically? Eventually tubes and caps and other things will fail. On that note, it’s good to be aware when things are going downhill. You might be able to shut it down before damage to other components like the output transformer occurs.

From too long of non-usage and/or bad storage conditions you can have filter caps drain their charge and then dry-out, and then that can cause a failure which can take other stuff with it.
How long is too long for the amp to not be used? I have no idea.
I let my tube amps go months at a time without running, but I rotate them so each one gets it's turn for awhile and none of them really go too long.
Modern caps are better and more durable from what I've read, and it obviously isn't as likely to be a problem if the amp is newer rather than older.
If a tube amp was stored in some ice-cold garage up in Canada for years then it should not be turned on without using a device to lower the voltage until it's had time to recharge itself.

My buddy had his Marshall for years with no problems. Then his kids started using it and never put the amp in standby. All of a sudden the amp started blowing fuses they wouldn't last more than a few minutes before blowing. The bench tech could never figure it out.

There's no benefit at all to using them to the electrical circuit or components.

I have no idea what your buddie's kids were doing to that poor amp . . . but the fact that the bench tech didn't say anything at all about using the standby switch should tell you volumes about how (un)important it is to do so.
