RE: anybody else fried a variac

I burnt up a brush on my little 2.5 amp variac. I went to the hardware
store and bought a motor brush (lots of different sizes). I cut the lead
and spring off, ground the carbon to the exact shape, and stuck in back
in the holder. I works perfectly again and only cost $2.65
