[Elecraft] K3s Issue

[David Blake]

I have a K3s #10113 that was involved in a lightening strike and just returnedfrom Elecraft after repair and upgrades. My KIO3B was destroyed "beyondeconomic repair" and a trace was burned and repaired on the RF board.  Ihad the general coverage module add as well as the 8 - 10W 2 meter xvtr.
All looked and functioned well until I attached an amp. I have a couple of ampsboth had worked well with this K3s prior to lightening and were not involved inthe lightening incident.
When I connect the amp from the K3s "KEY OUT" jack to the "RELAY JACK" on inthis case an Ameritron AL80A the red TX lamp on the K3s comes on.
I've looked through everything in the manual looking for a menu item that I mighthave wrong but can't find a thing.  Additionally I called a friend who has owned ahalf dozen or more K3 and K3s transceivers and he has never seen this.
I'm not very technical, but at age 75 had little trouble assembling the K3s from kit.
I would hate to have to send my beloved K3s back to Elecraft again, especiallyat $100 shipping round trip!
Thanks  --  73Dave -N4DB-
