So this downtime has me home and playing more than usual. Sometimes I leave the WD-800 muted when I'm between sessions, so the tube stays nice and warm and ready to rock when I get back after it. I'm under the impression that the more power cycles a tube goes through, the sooner it may fail. So there's 2 reasons I leave it muted if I think I'll come back within say 2 to 4 hours. But this downtime also gives me time to ponder whether I am being wasteful of energy, and what the nominal power consumption might be. Haven't been able to find that information. Even when I play loudly, I'm not using anywhere near the 8oo watts it has on tap, but I wonder how much energy it consumes while muted. I also question whether my concern about power cycles is overblown. I've seen studios and know people whose amps are left on continuously. My Compressore keeps the tube warmed up whenever it's plugged in, but the WD's manual says the tube needs to warm up a bit before you start playing. All things considered, what's the best practice, and does that vary with specific equipment? I'm interested in whether the TB cognoscenti turn off or just mute if they think they'll be back in a couple of hours vs say, 8 hours or longer. School me, Talkbass! Please answer.
