What a variac is:

Where to buy one: eBay, surplus stores, junk shops, online electronics
sellers, etc. Be cautious when buying a used one. One that has been
overloaded can have burned windings and/or a burned carbon brush, rendering
it unsafe at best and useless at worst. I can vouch for Michael, N0XY. If you
buy from him, you'll get a good one.
