300Bs - does leaving them on shorten their life?


New to 300Bs....tempted to turn on and leave on all day. Instead of powering up and down many times. But I think I heard that just idling will wear them out  more quickly.

Any guidance is appreciated!

Thanks!

If you have some uber rare and expensive 300Bs, you could use a device called a "Variac". This device limits voltage to reduce start-up stress on your tubes.
