I read this for the UFO:
SHORTING SPEAKER WIRES When your tube amp is on and you want to unhook your speaker wires without turning the amplifier off, it is an acceptable practice to SHORT the speaker wires TOGETHER. Yes, it’s true, this protects the output transformers from operating without a load. They can handle a dead short ALL DAY LONG without issue. This is JUST THE OPPOSITE of many solid state amplifiers, which as you may know, will blow up instantly if you short the speaker wires together, even for just a split second.
This answers my question not to worry about shorting it (don't worry about it), but I am confused about INTENTIONALLY shorting it while it is on and you are swapping speakers (something I do expect to do).
Can you actually hurt the amp by NOT doing the above, or just saying you can if you feel like it? I do plan to rotate speakers, and while the amp is on (though I would have the volume turned down all the way and have no signal playing).
Thanks!
