Elecraft KPA500 500 W AMP # 1597 READ: Elecraft KPA500 Linear Amplifier # 1597 - please read :
$1999 Delivered - check, Zelle , PP FF ok.
You are looking at a good working amp that has a minor issue.
In Standby, the HI TEMP light comes on,and it faults.
As soon as it's put into operate,the fault goes away,and it puts out 500 watts no problem.
Maybe a sensor telling amp that is too hot when it is not ?
This happens when you turn it on,so it is not to hot.
I am not a tech guy,but I am sure there are guys out there who can diagnose this easily.
Please email with questions,

FS: Yaesu FL-7000 HF amplifier: I have for sale a nice working condition Yaesu FL-7000 amplifier
Amp puts out rated power on all bands. Physically I would say its a 8 out of 10. Wired for 115v service. Tested good. Not too sure about the tuner because it was alway bypassed due to the fact that most of these amps fail due to the ATU going bad. Price is $1100 OBO. Can ship for cost or deliver to Xenia.; Listing #1766267 - Submitted on 04/27/26 by Callsign K2ZZ, Modified on 04/30/26 - IP: 172.59.211.155; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
