I've left it on standby for an hour before, really the longer it's on standby the better it'll sound when you come back to it. Generally I only turn the amp off when I'm going home/leaving the gig. In fact, sometimes if we're headlining and the venue wants to setup a backline, I'll turn my amp on and let it warm up while the other bands play, then I just show up on stage and go.
So to answer your question: yes.
late reply i know, but i just read it and wanted to add a quote from the Diezel guys:
Question said:]
Sometimes I turn the amp on, and play a little bit, but the switch it to stand by and go do something else and come back half an hour later and jam a bit more, then go do some other thing and so on, leaving the amp in stand by for more than 2 hours sometimes.
Is this safe? will this wear th tubes out faster?
Answer said:You are wasting way too much ressources and increase the CO2 emissions when you are doing this.
Standby is ok for the startup (even that is doubtful) and for short (!) breaks.
If you keep it too long in standby mode you can get cathode poisoning as well.
