[Elecraft] KPA-500 vs THP

[Ken Chandler]

Hello Jack et al
Thanks for your input.
Just would like to compare it with my SPE amp.
I can hook it up with 2 Radios (SO2R) situation, the SPE has a dedicated connector for so2r, 

The down side for me with the the SPE is the relays, they are extremely noisy, clack clack in QSK.
secondly it's just come back from Rome, Italy, for a Mod to the relays for QSK.
I blew up the relays last year during IOTA contest.
So I'm looking at the kpa500 as a possible replacement as I only use it on half power (400w legal in UK)
So I was interested in what the intended full spec was as I've been seriously looking at Icom amps as I have used them on CW contests in Cyprus with C4i contest station.
So yes, I know what I'm looking for but will compromise!!
The inbuilt  ATU on the SPE (3 - 1) amp is  good, but I don't hardly ever use it as all my antenna's are SteppIR.
