It is not a popular tube as it saw limited use and the socket is stupid 
expensive and similar to the 4CX1000A minus a screen contact. Alpha used it 
in the 70A and that is the only ham use Im aware of.

OTOH, it is what the 8877 should have been internally....a 1500W Pd, instant 
on, and a bullet proof grid.

The pull from a TV translator that was taken out of service and the socket 
($100 for both) has been in my HB 2M amp for over 27 years now and still 
loafs at 1500W. Backup spares were even cheaper (-;
