[TenTec] warming up of tubes

[Rick Westerman]

3 seconds is enough.

The 3-500z tubes are basically "instant-on".

However, I do not turn the amp off immediately.

If I have used it long enough for the cabinet of the amp to be
hot, I let it idle for a long time, giving the tubes a chance to
cool off a bit before I turn the amp off.  If you turn it off
immediately, the fan stops blowing (of course) and the tubes can
stay very hot for a long time.

I've been running 3-500z tubes for over 30 years and have never
had any problems, even though I begin using them immediately.

Can any one tell me how long must I allow the tubes in my
centurion warm up before use ?   John
