Hello Andy. Well, I measured the voltage at the input, and output of the lathe transformer and everything is ok. The fuses are OK too, so I'm thinking about the capacitors as dave pointed out. Please don't think it has nothing do to, every help is well received :). -- *Leonardo Marsaglia*. ------------------------------------------------------------------------------ Want fast and easy access to all the code in your enterprise?
