Master volume.

[boogieman60]

I blew a STR440 output tube in my V when I turned on the standby switch. I had been noticing a pop when I came out of standby....So I started to turn the master volume down to 0 when going in and out of standby...no problems since.

Most tube problems will arise when you flip the switch because it sends all the power to the tubes then . That not uncommon

have you noticed how when you turn on your amp it takes a min or two for a signal to get there, thats doing what you are doing already for you. As the guy above said any tube problem is gonna occur when you turn on your amp and let the electricity flow through.

I do that most always with every amp. I started doing it long time ago, not because I had tube problems, but because I hated that I (and other people in the room, that may not have earplugs) didn't always know how loud it's gonna be. A sudden very loud sound that stem from simple carelessness is one of the little things that make me pissed off. Before I turn an amp on, I turn the master volume down to zero. Before I turn to standby and power off, I also zero the master volume. It's particularly wise if you lend your amp to someone else. I'm so used to doing it I don't even think about it anymore. It's just like morning routines. You do them every day but when you try to recall a vision of the exact moment you did it last time, you probably can't. Minding these kind of little thing can make our working enviroment much more comfortable, and failure to do so is simply unprofessional. At least this is my opinion as a working musician.

I have all channels in 10 watts mode and masters in 0, output and solo in 0, also mute is on, before starting the head and before shut it down..oh, and also the guitar volume pot and tone are rolled back..this way, I think tubes are not under pressure at the beggining and when shutting down :mrgreen:
