Or, you could go over to that "auction" place and buy a real power supply, like Kepco or Lambda or ... (one marked ..."Made in U.S.A."...). If you want the "Cadillac of the Industry, find a Krohn-Hite.

They're sold under several brand names, and there are several versions, all basically the same. I'm guessing I'm not the only one who was attracted to their low price. The fix is easy, though it took most of the day to figure out. Contact me if you need it. 73, Scott K9MA -- Scott Ellington K9MA Madison, Wisconsin, USA [email protected] ______________________________________________________________ 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] ______________________________________________________________ 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]
