Yes...with a tube amp on standby, it is safe to change speakers. The main concern here is potential flyback voltage generated in the output transformer with no or too high of a load on the amp. However, for said flyback voltage to be generated in the output transformer, the amp has to: 1)not be on standby, and, 2)also have an input signal applied (or some sort of internal oscillation malfunction).is it safe to unplug a speaker cable from an amp head from one speaker cab to another while the amp is on standby - I'm told that it's OK as long as standby is engaged but I need some expert opinions
What he said. ALL the time. Never a problem.I switch cabs all the time in standby.
