The General Radio 1422-D Precision Capacitor was introduced in Catalog Q (1961) and remained available through Catalog 1978.
The Type 1422-D is a laboratory quality, precision variable capacitor specifically designed for audio frequency applications, an updated design of the 722-D with an aluminum case and redesigned frequency control knob. It features two ranges, 35 to 115 pF and 100 to 1150 pF with connections using Type 938-A Jack-Top binding posts plus ground terminal with shorting link.
The set value can be read directly from a drum mounted on the rotor shaft. A correction chart is mounted on the panel for that particular capacitor.
The rotor is mounted on preloaded ball bearings in an aluminum casting, driven by a precision worm drive.
