No, I don't know the specific reason, but was told that the speakers provide a load on the amps, and especially for tube amps, it's not okay.
is it ok to leave a tube amp on without speakers connected
I'm blessed to have two amps but one set of speakers in my listing room - all tubes. Instead of cutting off one to listen to the other, I would like to listen to the other without powering off the one i'm not listening to.
Question: Can tube amps be powered on without speakers connected for hours at a time?
