 I have found a motor driven variac, 10 amp I believe with a steel
 control box
 that has a cover. I dont know much about them and its rather expensive.
 Im
 thinking of buying it but does anyone know how they operate? Is there a
 control you set which drives the gears and sets the voltage? What is
the
 advantage? I want it for a larger coil Im planning but if it has no
 advantage
 Ill just use a dial manual type. This is a large heavy unit,may be 15
 amp and
 they want 170.00 for it.   Stephen Sanders

Stephen,

You didn't say what the voltage rating is.  For a large coil (I am
assuming
several kva) you want a 220 v variac.  $170 for a 15 amp variac is too
much.
 I found a 28 amp 220 volt model for $100.  I know others have found
these
for under $200.  It sounds like this was set up for remote control of
some
heavy equipment - not needed for a Tesla coil project, but the parts may
be
useful for something else.
