Gentlemen,

This single band 7 MHz amp for amateur usage is conservatively rated at 20 kW 
output. Exciter is an Icom IC7800.
According to the builder of the amp is does 20 kW out without abnormal blower 
noise levels or a burning smell from the RF deck. A 30 kVA 3 phase power supply 
is used, generating an unloaded B+ of 8 kV DC.

Cheers, Dick
