1936 Wobbulator

Wobbulator

Eighty years ago, the well equipped radio service shop could very well have been equipped with a Wobbulator. Shown here, in the April 1936 issue of Service magazine is the Model 180 Wobbulator, manufactured by the Triumph Manufacturing Company of 4017 W. Lake Street, Chicago.  The unusual name is for a signal generator covering 100 kHz to 30 MHz.

The Wobbulator should not be confused with a Gonculator, a device used only on submarines.
