 Elecraft KPA500 KPA-500 Factory wired

Factory wired KPA500 for sale surplus to my needs. I have another one but not doing SO2R high power.
Factory box, no issues, appearance 9-10, non smoking shack. $2,000 local pickup or you only pay actual shipping and insurance from 27613 North Carolina. It's really a great amp, quiet, no relays and just like a 500W transceiver.

 Expert 1KFA  
Expert amp 1KFA works great no problems, this is the version 3 which I think is the last version of this amp, 15-18 watts in will get 1K out, I always ran the amp on half power (600 watts) it is all automatic, I have the manual, the factory box and the carry case I have pics. Asking $2300 shipped in USA would trade for Icom 7700 or a Icom 7610

In good condition. I just recapped, replaced balance resistors and went through the unit. This has a pair of 3-500z Eimac tubes.
Asking 750$ pick up only off of I-81 near PA WV VA and can meet within a
reasonable radius.
