If the hybrid amp were mine I would leave it switched on all of the time unless leaving the area for more than a couple of days.if tube life is shorter than you are happy with,you could always fit a standby relay and switch interupting the B+ power to the tube section so that the solid state amp and the tube heaters stay on all of the time keeping the amp close to operating temperatures with less risk.
Always On?
I've was given a suggestion that by leaving audio equipment always ON will result to better quality sound.
I have hybrid amp (tube preamp and solid state amp) and I am not sure if I could do it safely for vacume tubes... As I understand the tubes have limited hours life. If I would keep an amp always ON the tubes will be On too. How long would they last if running them 24 hours a day 7 days in week. By saying "to keep them ON" I mean not simply keeping amplifier plugged to electric outlet but by never pushing Power ON/OFF button off. How many of you never turn the tube audio equipment off?
P.s. I've been rereading a user manual for my tube phone moving coild pre preamp (Music Reference) where its manufacturer suggests the same thing - for best performance always to keep it ON.
