I remember bangin' on the side of old tube TVs
I have read that it is not good to turn on a tube head with no cable running to the speaker cab.
I always have a cable plugged to the cab from the head.
What will happen, and will it hurt it every time if one forgets to have a cable in place?
It depends on amp wattage and how robustly an amp is built, but smoke followed by an expensive repair is the usual result of failing to plug a speaker load into the back of most gig-size tube amps. The speaker is part of the output circuit.

But now I'm an old, crotchety man and I use standby switches because I dig traditions that died before the world was born.
