The tube is just a little feller at 5.8KG or 12.6#
7.4" in diameter and 9.25" tall.
But the grid is 200 watts dissipation so there's insurance for the guy 
tuning up on the wrong band.
Max AB1
10KV @ 6 A, 2 KV on the screen and a whole -1.5 KV on the grid.
But it only goes to 110 MHz at full ratings. I guess it'd be OK on 
2-meters at reduced ratings as it'll go all the way to 225 MHz. <:-))
Guess I'll have to pass though. I doubt I could get Consumers to run 3 
phase into this subdivision and I couldn't afford the coax connectors 
I'd need.
Man, just think of the band switch for 1.8 - 30 MHz bands!

Well, back to reality and 1500 watts QRP.
