the "Kick" discussions responding to my question about why caps would fail in the low-band filter relay firing circuits on my K2/KPA100 have been very interesting. That there could be such a kick was not a surprise to me so much as that it could be so enthusiastic. Don Wilhelm reports that the "relay driver" in the kpa100 has such diodes. Where? inside the relay enclosure? It doesn't seem like shunting off this higher voltage in the octal driver would work more than once. Suppose the diode is in the relay. Because some of these diodes may have failed due to the excitement of past ESD events, how would I check to see which ones were ok? Would the Diode checker on my fluke check a circuit which had both a coil and a diode - I;m assuming they would be parallel. Or is this whole line of reasoning nuts? Should I go back to idea of stocking up on 100 volt caps and replacing all of them the next time one fails? 73 AI4TO John Ferguson M/V Arcadian **************New Deals on Dell Netbooks – Now starting at $299 (A HREF=http://pr.atwola.com/promoclk/100126575x1219939010x1201342897/aol?redir=http:%2F%2Fa d.doubleclick.net%2Fclk%3B213771626%3B35379597%3Bw) ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net
