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.
