1302-A
The General Radio 1302-A Oscillator was introduced in 1948 Catalog L and remained available through Catalog Q 1961. The Type 1302-A is an R-C oscillator using a modified Wein Bridge to determine the frequency at low distortion. It uses include audio testing or as a source for bridge measurements. An example is its use as a generator in the 1610-A Capacitance Measuring System.
