I had a similar problem with my K3. Suspecting a power supply problem, and after reading: http://www.repeater-builder.com/astron/astron-intro-stuff.html I found that the RS-35M pass transistor mounting screws were slightly loose, i.e. I could easily tighten them perhaps 1/8 turn. After adding "split-ring" lockwashers to the pass transistor mounting screws, the problem has not recurred. Also, I have added fans to the backs of the heatsinks. The RS-35M no longer gets hot, like it used to. -John AC6SL ______________________________________________________________ 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]
