Variac Troubles

Hi All,

	I just bought what APPEARED to be a 1256 Powerstat variac.  The trouble
is, it saturates beyond 120 VAC in.  The new unit is identical to my
existing 1256, except for the wiring beneath the binding posts.  The new
unit looks like it uses the whole winding, but there are wires that go
someplace INSIDE the core.  I can't tell where these wires go.

	Is it possible that this variac uses a different core material, which
saturates more easily?  I say again that the two units are IDENTICAL in
every way other than that stated above.

Please help, I'm stumped :-P.
