The Type 107-J is a variable inductor or "Variometer" of the [[wikipedia:Ayrton–Perry winding|Ayrton–Perry winding]] design. It contains two circular coils arranged within one another, a stator or fixed coil and a rotor coil attached to a calibrated inductance dial. By changing the orientation of the rotor coil, inductance can be varied. The leads of the two coils are brought out to four binding posts where connections determine series, parallel or mutual inductance settings. Shorting links are provided for this purpose. The 107-J featured a Bakelite panel and walnut case. A tag attached to the panel displays the actual values. | The Type 107-J is a variable inductor or "Variometer" of the [[wikipedia:Ayrton–Perry winding|Ayrton–Perry winding]] design.
