My favorite triode for 1500 watts all day is a single 8877. 4KV and 30 watts
drive.

Used 8877s exist and are more than capable for long lives. Some of the 8877s
at K3LR have date codes from the 70s... still going strong

Eimac specifies 890W for a single tube at 3.5KV plate voltage and 740W at
3kV.

The 3-500Z is an excellent tube, but 1500 W isn't reasonably available 
out of a pair, even at increased plate voltage
