That would make me search my junk box. It is also a bit close to the 42 volt rating of my new drivers. Rich is not on of the bennies of being retired, darnit. In fact, I may have something I can use now that I think about it. I believe the supplies I use in series for EDM when I need to, could be paralleled as the 2 in series make about 80 volts, which when used for EDM, with a 25 ohm limiter and a 10 UF capacitor, work very well but sent me to the truck for my rifle range muffs, as it is ring your ears noisy. Now if I can just recall where I got them from because I don't want to tear that rig off the wall. I hate it when that happens. :( > > I'm currently running on a 28 volt switcher > > good for 12.5 amps if actively cooled. 42 volt rated drivers, so I > > would like to locate a higher voltage (36?)supply.
