Relax and enjoy your music.
Its not like running a motor without lubrication.

It would be easy to short one of the tube's pins, especially if your sockets have a metal post in the center.

I've hot swapped quite a few 6992s in an amplifier when the manufacturer said it was OK to do. It used "global-feedback". Retubing it just required minimising the voltage difference on the last dual triode.

And, remember that you probably have at least 100 volts that can wake you up if you slip! The bite won't be bad. But, you can develop a habit of not pulling your AC cord before changing tubes, and some day, do that with an output tube with more than 100 volts on it.
