When to Poweroff amps and preamps

MC your priceless, what are you gonna do if you ever hear a Reel to Reel you like. They are easy to like too, I mean REALLY like.. :-) Just sayin'

I'd just like to add, there are a few, SS power amps, you want to shut off.
Class A  SS gear will just run to hot to leave on...Class AB older amps can run on the hot side. It depends on a few things.

Bias setting for one, when idling..It can make a BIG difference, there is a trick or two, to be able to leave the older AB stuff, on.. (for a while)
I have Adcom gear, in one of the shops. LOOK out.. when they are warmed up..VERY good gear if you know what your doing..VERY bad if you don't. Speaker blowing baster$s, if your not careful.

I turn THAT setup off.

UNLESS it's Class Ds, some Gs, or has a stand by, and is a power amp, OFF.

MC did say digital, BUT SS and digital, aren't exclusive. I know what he means. BUT there are THOSE, that will pick it apart.

Ncore amp modules (on), and my current  Mac gear (stand by), I leave on.

Soon though, my C2500 will be fixed, BUT it is both DAC and valves, it gets turned OFF.

The fall/winter/spring, monitor amps will be swapped for valves, (I can hardly wait). ALL the stuff currently stays ON, Three weeks or so, OFF

 Anything with tubes (valves) gets turned off. It's just not safe..

Now that I'm thoroughly, confused, I'll go in the shop and warm up the C20, MC240 (all valves) and a class d Behringer 12K, about 10 minutes of play time... It's a Class D, BUT I disconnected 2 of the three fans and put the last one on a flipper switch. QUIET, at 2 AM, wonderful. I get CLEANER power too. 2-4:30 or so..

Time for the morning walk...and feed the rabbit (Junior)

heavy - is your MC240 stock ? Mine is 1961 and super modified.... sweet amp for sure.

<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>

All 5, MC225,2x240s,275, and a pair of 60s are all stock, I have all the parts for PS, upgrades and pio caps, and a pair of 24k cases for the 60s.
The one 240 though has EU caps in it, so they didn't self destruct, like a lot of the other bumblebees. It is VERY special, indeed.
 I did mod up a 275 GG, that I managed to blow up a while back, (cable drop), it's quite a bit better than stock. Still it's a KT88 unit.. Not my favorite valve. I'm a 6550, El34, 6L6,  guy these days.. :-)

Summer/Winter, wahoo, night and day where I live. 33-35 is considered cold here, and it is, if you get caught in it. But I've seen, 45 at night, and 105 in the day, two days apart. Tube gear is not real partial to a REAL cold starts. My Cary stuff can pop a fuse with a real cold start too.
