Andy do not glue to date of first post date in the link. Please follow and refer to its revision date in the end of the document in the link as it keeps updated as much as possible.
Simply check the revision label on the PA/LPF board of your KPA500 and if you have rev. D9 or earlier with surface mount board (NO earlier rev. A or B with thru-hole yellow capacitors board) then the mod is for you if needed. As I mentioned it is not neccessary to do it if you hate to open and dismantling your KPA500 if all is currently working well for you... There is tons of amps that works like champ even they are old and not modified. So if you have not issues and do not want to make prevent mod then stay calm. BTW: yes it is official mod, Elecraft parts kit: E850607 good luck, Petr, OK1RP ----- 73 - Petr, OK1RP "Apple & Elecraft freak" B:http://ok1rp.blogspot.com MeWe: https://bit.ly/2HGPoDx MeWe: https://bit.ly/2FmwvDt -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ 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 Message delivered to [email protected]
