to play , 2mns of heaters on tube are enough to safely use the tubes !

but, to make it singing, a warmed caps and power supply (current stabilized) is better, so 20- 30mns of warm up is required

Yes, 2 or 3 mins in the Standby mode are enough but 2 or 3 hours or more in "Power On" mode for an extraordinary sound...........

I give my tube amps 2-3 minutes on standby before playing at mild volume. My MkIV in particular seems gutted unless it's been played for 15+ minutes. I never noticed before having the MkIV that the MkIII also improves after warming up, but it doesn't take as long to reach nirvana.

Mesa says 30 second warmup, but what would they know, they only designed the durn things.
As for hanging upside down, etc., the first Boogies were modded Princetons, which, surprise!!! have hanging tubes. It wasn't broke, and they didn't fix it. Once they got into the "real" amp head business, like Peavey, Soldano and everyone else, they copied Marshall.
Oh, dear, I'm boring myself...
I once played a lot of one-nighters, where the trusty ol' Mark III sat in its road case in the cold, cold garage, then back of the cold, cold truck en route.
(And this is SoCal. I can't imagine Minnesota. Yikes!)
Once flipped on, it seemed to take a good hour or so to warm up and not sound brittle. It got to where I'd just leave it "on" for the entire gig after warm-up, because I thought it sounded better. Works for me, YMMV.

Mesa copying Marshall?
i found both schematics structures rather differents
Tube guitar amps builder doesn't need to copy anyone , as the technology is simple !

this guy build great amps , and trying to get Marshally tones , without copying

a tube amp power supply need 20mns at least to be fully stabilized (current and heat) waiting 4 days or 100 mores will not add any heat or stibilized current!
