    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.
