[Elecraft] switching a heath amp

[riese-k3djc at juno.com]

May be worth the additional key relay,, my Kenwood TL 922 quit and I can
barely move it 
let alone try to repair it,,, Not sure what to do wit it but that is
another story
I keyed another SB200 with an ICOM rig and built a little 5 volt key
relay
but it used an external wall wart. I may dig up a 9 volt relay and key it
using a 9 v battery
may pick up a heath SB220 fer 60 bux from a local shouldnt be able to
tell the diff
600 v 1200 watts
