Run it class A and key it with no carrier and the shack will be nice and 
toasty by the time you get home.
With today's remote control for stations being relatively simple it 
should be relatively simple to turn on the rig or any portion while on 
the way home from work.  That would rarely work for me as I'm retired 
and it only takes about 1 minute to make it from the house to the rig in 
the shop and have every thing fired up.  I've missed DX just because my 
current amp takes 3 minutes to warm up. Of course it doesn't happen very 
often, but it's still an aggravation. <:-))
Of course the 4CX3000A7 is almost instant on although it takes a step 
start or ramp up of the filament voltage @ 375 watts
