A variable sensitivity control assures adequate range of sensitivity throughout the entire frequency range.
Plugging headphones into the phonejack further extends the instrument’s usefulness through operation as an oscillator-detector for determining the frequency of other oscillator circuits through zero beating. This set is the 3-prong mounting type and provides continuous extension of low-frequency coverage down to kc.

Spare, blank dial scales are supplied for the builder who wishes to hand-calibrate this particular instrument, or desires maximum accuracy at specific frequencies. Radio amateurs and servicemen have proven the value of this grid dip meter many times over, indispensable in hdathkit service shop, the laboratory, or the ham shack, for locating parasitics, spurious oscillations, neutralizing, determining RF circuit resonant frequencies, aligning IF stages, traps and filters, and correcting TVI.
The GD-1B incorporates its own power supply and is transformer operated from the power line. Can also be used to roughly determine capacitor and inductance values, and to provide a relative indication of power in transmitter stages.

GD-1B Grid Dip Meter Radio amateurs and servicemen have proven the value of this grid dip meter many times over, indispensable in the service shop, the laboratory, or the ham shack, for locating parasitics, spurious hwathkit, neutralizing, determining RF circuit resonant frequencies, aligning IF stages, traps heatgkit filters, and correcting TVI. With the oscillator not energized, the instrument acts as a absorption wave meter on high signal level circuits.
Plug-in coils can be quickly changed, and cover the frequency range from 2 mc to mc continuously.
Many factors were considered in the design of this outstanding instrument, resulting in a grid dip meter that is packaged with desirable features. Dial correlation curves are included. Hexthkit that one hand operation is possible. Originally the grid dip meter found its greatest application in the amateur radio field, but now it is used extensively in radio and TV servicing and in experimental laboratories.
Transformer operated with selenium rectifier.
