Thanks Don (W3FPR), Monty(K2DLJ) & Ray (SM5XLP) for your helpful replies.
I have now studied the circuit diagram of the KPA100 and identified the 20/17M filter section you refer to. This weekend I will try re-flowing the solder joints of the 5 capacitors & two toroids and will check continuity between Test Point 2 & the PL 239 socket all as Don detailed. I will let you know the results, thank you 73 de Ray, G3XLG ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
