The General Radio 1422-N Precision Capacitor was introduced in Catalog Q (1961) and remained available through Catalog U (1970).
The Type 1422-N is a laboratory quality precision variable capacitor specifically designed for RF applications. It's an updated design of the 722-N with an aluminum case and redesigned frequency control knob. Its direct reading from a drum mounted on the rotor shaft. The rotor is mounted on preloaded ball bearings in a aluminum casting driven by a precision worm drive. A correction chart is mounted on the panel for that particular capacitor.
Specifications
- Capacitance Range 100 to 1150 pF
- Dial Accuracy: See Experimenter
- Maximum Voltage: 1000 V peak
