Re: [CAD_CAM_EDM_DRO] Re: Charging Capacitors

this is correct, and maybe even raise the voltage very slowly over a period
of 10 or 12 hours or more. i used to watch the current of leakage but you
need electronics test equipment. even if you take several days to get the
voltage up to the limit will not hurt anything. cul brian f.
