[Amps] Flex Power Genius XL 2KW amplifier

[Victor Rosenthal 4X6GP]

I don't use full QSK for ragchewing or running stations, in which case I 
use semi-QSK with a short delay adjusted to allow the relays to open 
between words. I do use it when I am trying to work a DX station through 
a pileup, and I want to be sure I catch him if he comes back to someone 
(hopefully me).

However, a clunky open-frame relay like the one that came in my TL922 
would drive me nuts even with semi-QSK. I always have used vacuum relays 
in my HB amps and installed them in commercial ones that came with slow 
relays.

I am also convinced that many TL922s were damaged by hot-switching as a
result of that slow relay.

One of the best commercial amps I ever had was an Alpha 86 with PIN 
diodes. I know that some people had trouble with them, but mine worked 
perfectly for the several years I had the amp.
