I recently repaired my K3 LPA by replacing one of the output MOSFETS and making other modifications per Gary Surrency. I had to re-adjust the bias on the finals using an external ammeter and was able to complete that successfully. The LPA now puts out the full 12W. However, the front panel display shows that the K3 is always drawing aroung 24A when I know it is less than 1A on the external meter. The reading is the same whether or not I have the KPA3 installed. I still haven't had a response from Gary so I thought I'd ask if anyone else has seen this. I have checked the output of the current sense U1 and it is correct.
Anyone have any ideas??? Thanks, Russ N3CO ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
