If something goes wrong, there would be HUGE explosions and the amp would be reduced to smoldering rubble. Of course, this can happen with an isolated supply, as well, but other than the guy who took the insulating heat conductors out of my amps, that pretty much has never happened. The transformers don't have to be real large, and the "step-down" transformers used on gear that ran off 480 V can be reset to give you 60 V AC for 84 V DC. That may be enough. otherwise, you can set up a 1:1 isolation transformer with a buck transformer to get most any voltage you want. The buck transformer can be much smaller than the isolation transformer. > also on the way back to mo to happen in the next 60 days do you have a > store front or let random internet strangers poke around ??? > Pico Systems is basically my home basement! If you wanted to drop by and see my shop and talk about CNC stuff, I'd be glad to see you.
