Just be careful with the grid current and they will last longer than you
will. Figuring 5 hours of transmit time per day, the tubes should run about
11 years.
As to warm-up, Alpha has a good start circuit and when it's ready to start,
it will. Same true for the Tentec Titan. As I see it, there's no sense
boiling off a couple of hours of electrons from the cathode of those
expensive tubes.

Subject: Re: [TenTec] Centurion
again, an interesting discussion on the Getter !!.. I guess a lot of us
have amps and this is good info. I just bought a alpah 87 a, and I let
that
cook for a couple of hours before applying any rf to it. those 3CX800A7
tubes
( 8875's ??) run about $900 for a replacement pair, so I want to be Real
careful on them.
I love the give and take on this reflector.
good job Guys..
