STANDBY on tube amps - what's your practice


Was just wondering....I always let my SF Power Amp 1 warm up as well as cool down by using STANDBY button (about 10 min for each) and only then I turn on/off the main power switch. But if I take a 30 min or so break between listening sessions, I just leave everything as is...full power on....if I walk away for an hour or so - I always put the amp in standby mode.

What's your practice for tube amps?
How much you'd let your amp stay on (full power) vs on Standby?

Thanks!

It's very important to wait until your tubes' heaters warm up their cathodes, and create an electron cloud around them(in "standby") before applying plate voltage(B+, or operating voltage). Otherwise you'll wear out the tubes via "cathode stripping". Your procedure is an excellent practice of that understanding. My tubed equipment remains on "standby" all weekend, or over holidays, because I know I'll be listening to the system a lot during those periods. Other than that: I turn them off, and back on("standby" for a few minutes, then "plate voltage") about an hour before I plan on listening to my music. SS stays on 24/7/365(unless I'm leaving town).
