Keeping tube filaments on obviously wears out the tubes faster.
Follow Ups:
They're not running full bore in standby. Glowing and warm is all. Every system I've ever owned had/has this feature and I've never lost a tube due to filament failure.
Going from stone cold to full power in an instant is what kills filaments, not low power standby mode.
Wrong. Filament life is hours in use either at full current or minimal current. Turning on and does not burn out filaments.
We will have to agree to disagree on this one.
just look at incandescent lightbulbs...How many times have you seen them burn out at turn on as opposed to lighting the room for 20 minutes?
Right now for one of my room lights I have an incandescent that I'm using a variac on and the bulb is going on 3 years now. I always start it with 60vac and bring it up when needed. I have to do SOMETHING with the few that I still have
So then, slow turn on with an indirectly heated rectifier like a GZ34 will and does increase lifetime
