DC Output.....polarity doesn't matterLuis G said:You want the output to be AC or DC?
(not that I can help too much with that, but I'm sure one who can help would ask the same).
A brief search returns only variacs with AC output, but I'll continue looking. Thanks!chcr said:Well, I've got one but don't remember where it came from (had it for eons, y'know). Can you pick up a used variac or some such? I'm pretty sure I've seen one that was 120VAC in and 0 to whatever DC output with a meter.
