I had a NOS JAN Philips 12AT7 flame out in my Jolida last year...harmed nothing, replaced both 12AT7s under warranty (thank you thetubestore) with nice matched CV4024 Blackburn Mullards, and have been living happily ever after. I don't leave the amp on when I'm out, and turn my entire system off at the end of the day or if I'm gone for more than a few hours. The NOS Mullards do provide an entertaining flash on startup, and I don't think new (current repros from New Sensor) ones do that...at least the 12ax7s I have in a guitar amp.
When to power off a tube amp?
So I just got new tubes for my Lyr and really don't want to damage these tubes and want them to last for as long as possible. So I had a few questions and was hoping you guys could help me, thanks.
1) Should I turn off the amp if I am going to away for like an hour or so? Would that decrease the life of my tubes more than leaving it on that whole time I am not using them?
2) Should I let my tubes warm up before using them? If so, how long should I wait?
3) Is unplugging my headphones before turning off my amp necessary?
And just a random question out of curiosity, what if you use two different tubes in a tube amp? lol.
Thank you guys, any help would be much appreciated.
