[Amps] 3-500Z cool down time

[Kimberly Elmore]

True enough; I was simply statingthat the 3CX1200 is a ceramic replacement for a glass envelope. It's a fine tube, though it requires a fair bit more drive. That is, aparently, the price paid for a high grid dissipation rating. It's easier to drive when running 4 kV B+, though. At that voltage, I never fail to acieve full output with a 100 W rig on any band.

Yes, but that's a very expensive tube. I was thinking of a ceramic
3-500Z for the same price as glass. 

For what they are asking you might as well get an 8877. Different
socket but lower drive and more output.
