I have an Astron RM-35M (35Amp) that I just tested by shorting the output and it doesn't blow the fuse. I think I would be looking for something in the primary circuit that might be shorting like the transformer primary or the surge arrestor or maybe the wiring. I have seen transformers that short after they warm up a little. Bill - WA0CBW In a message dated 12/25/2008 10:11:11 P.M. Central Standard Time, lar...@hotmail.com writes:

As I recall a shorted output simply folds back, like you say. I also have two Astrons here on the bench. One is a VS12, the other is a RS12. When the output is directly shorted with heavy wire they both simply fold back. Shorted them dozens of times; never a blown fuse. Laryn K8TVZ ------------------------------------ Yahoo!
