Hi Folks, I have had another PA transistor failure in my 2003 vintage K2. The transistors have been replaced several times over the years and the board is now a mess. I'm planning to rebuild the PA on an external board with a proper heat sink mounted on the back panel of the K2. This will involve taking the secondary from the driver transformer on a piece of coax about 6 inches long. My query is what impedance is the secondary of T2 designed to work into and will I have a problem taking this to the external board? I've never liked the design of the mechanical fitting of the K2 PA and always regarded this as the Achilles Heel of the rig. Suggestions appreciated. 73 -- John Petters www.traditional-jazz.com Amateur Radio Station G3YPZ ______________________________________________________________ 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
