I'm currently using a Mesa/Boogie M-Pulse 600 and am going into the studio to do some recording next week. Now, I know that running an all-tube amp with no load is a bad thing. What about hybrid amps? The amp in question has a tube preamp that drives a MOSFET power section. Can I safely run this amp with no load? I could always just plug it into one of our 8 ohm floor monitors, but its more a thing of curiosity in general.
