I'm with Evan, Neil. Be certain you do this in a quiet environment. The
instant you perform an increase and you hear a frying/crackling noise, BACK
DOWN 'til you don't, and give it an hour or two at 5V or 10V lower than
where the noise started. I actually had this non-destructively happen, and

If my memory serves me correctlyA variac is a variable
"autotransformer."
Autotransformers have a single winding and, therefore, can not be used
for isolation purposes.
