[Elecraft] KPA5

[Paul Ormandy]

Hi all,

Just calling FT4TA on 20m RTTY at about 500W, heard a loud crack from 
the KPA500, now not amplifying. Still powers up and passes RF thru from 
the rig but no amplification. No smell of burnt silicon either, which is 
a good sign I guess!

There was no Hi Input or Hi Refl Pwr warnings... same all bands so 
assume not in LPF section.

Going back to work soon (am on a lunch break) so would appreciate advice 
what to look for.

Cheers,

Paul
