 For any band up to 20 meters they kick butt and love high voltage.

The 813's typical operation is to 30 MHz. I ran a pair on 10 meters
with 3350VDC on the plates.
Drove them with a Swan 500cx until the carbon plates many red
hues...Couldn't burn them out.

1983 "The Radio Amateur's Handbook"
Freq.: 30 Mc.
Plate V. 2500
Plate MA 125
Screen ma. 20
fil 10v 5A
Screen Volts 800
Cin PF 16.3
C gp PF .025
C out PF 14

Typical output AB2 two tubes is 650 W
