[Elecraft] KPA-500 Features and Pricing

[Graham Kimbell G3TCT]

I currently use an Acom 1000 amp on 80 and 6m and a homebrew 
semiconductor amp (160W o/p) on 4m.
The features I really like about solid state amps is their efficiency 
(50-60%), and zero warm up time. I often find on 6m that I can hear 
interesting but very weak dx that needs the amp, but I have to wait 
nearly 3 minutes for it to warm up, by which time the dx may have 
disappeared.  By contrast the solid state PA takes no current on standby 
and is available instantly.

My 2p worth
