It really doesnt need to be 200 watts on a home machine. Even 100 watts
will work fine.

All you got to do is take your ohm meter..tweak it the slider to the
proper ohms rating for your vfd..and hook up some wires.


Be careful when using a slider to set the ohms. You'll need to derate
the wattage proportional to the setting. ie 50% of the ohms is 50% of
the wattage. http://www.ohmite.com/catalog/210_series.html
The other thing is the reliability of the slider connection is
much lower than the reliability of a fixed resistor.
