[Amps] Ameritron EBS-1 in AL-1200?

[djl at andlev.com (Dan Levin)]

I'm pretty clueless about such matters, and would appreciate any advice.

What do folks think about the importance of, and/or utility of, installing
the
EBS-1 electronic bias kit in an AL-1200 that is going to see heavy duty
contest use?

At the risk of demonstrating to the world my complete lack of undestanding
of high power amplifiers, is it correct that this kit basically senses input
RF,
and biases the tube to cut-off in the absence of input RF - thus reducing
the
"circulating currents"?

Thanks!
