why do you have to power down to switch? i can switch mine back and forth without missing a beat. triode is less rated power but i have found it to sound even more powerful than tetrode.
Switchable Tetrode - Triode please explain
I am using a VTL ST-150 which is switchable from 175 watts tetrode to 80 watts triode . Can anyone please explain the pluses and minuses of these two modes ? Thanks!
