[R-390] Variacs

Of course, a variac can be wired so you cannot get a boost. That is, the output is always equal or less than the input, never higher.

Les & Gang:
  Helpful -- maybe.  But be careful of the variacs with a
range switch, typically 0-120 and 0-140 volts nominal -- very nominal.  More
likely to be 0-130+ and 0-150+ with more typical input voltages.  Keep it on
the low range and put some tape over the switch.
