    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.

    When I was a little girl, car radios had tubes. You could crank them up and they'd distort like a guitar amp. One speaker in the middle of the dash, AM radio. The speakers were horrible sounding, and the combination of a crappy speaker and rock and roll song cranked to distortion? Perfection!

    I also used rotary dial telephones, and rode in cars without seatbelts.

    But now I'm an old, crotchety man and I use standby switches because I dig traditions that died before the world was born.
    If something is too hard to do, then it's not worth doing. You just stick that guitar in the closet next to your short-wave radio, your karate outfit and your unicycle and we'll go inside and watch TV.
