example of the breed ever made. Comes with original copy of General Radio
“Handbook of Voltage Control With The Variac Autotransformer.” This little
treasure is a 40-page booklet published in 1963 by General Radio Company which
"designed, patented, introduced and manufactured" the Variac sometime around
1933. It is in an 8.5 x x11 format. The booklet contains 12 pages on Theory and
Principles, 19 pages on circuits using Variacs and 8 pages on specific Variac
applications. All the GR Variac models are discussed in detail including
connection diagrams and so forth. One section shows how to use Variacs in
series and parallel applications (with the use of a choke to prevent current
oscillation when the 2 Variacs' brushes are not perfectly synchronized).
Motor-driven Variacs are also discussed. In short, this may be all you ever
wanted to know (and then some) about the mighty
Variac. $150 for W10MT3 Variac with original GR booklet.
I have 2 reprint-quality copies of the GR booklet also available for $10.50
each PPD.

ohms. Dirty but will clean up to excellent. Untested but probably working fine.
