on larger amps like Fender Twins, Vibrasonics, or Marshall where voltages exceed the vacuum tube manufacturer's ratings the Standby switch is a good thing.

my old 1958 Gibsonette has an on/off switch; that's it.
my Fender Vibrolux Custom has the Standby. I always use it.]]> Live Sound dogbite https://guitarnoise.forum/live-sound/tube-life-and-standby-switch/#post-168838 https://guitarnoise.forum/live-sound/tube-life-and-standby-switch/#post-168834 Tue, 28 Mar 2006 18:22:47 +0000 Live Sound Ricochet https://guitarnoise.forum/live-sound/tube-life-and-standby-switch/#post-168834 https://guitarnoise.forum/live-sound/tube-life-and-standby-switch/#post-16646 Tue, 28 Mar 2006 17:01:54 +0000 it was really more about how to use a Standby switch on tube amps.

turning On a tube amp one simply flicks the switches to ON.
wrong.
there needs to be a warm up period (a minute or so) . the tubes need to be warmed by a low voltage applied to the cathodes;
if high voltage is applied the tubes life will be shortened and possible damage can occur.

so in turning the amp on the recommended procedure is

Standby to OFF
Power to ON
wait one mionute then
StandbyON


does this make sense?]]> Live Sound dogbite https://guitarnoise.forum/live-sound/tube-life-and-standby-switch/#post-16646
