General Radio Type 1422-OD Precision Variable Capacitor

One of my favorite pieces of equipment. Unbelievably well made. It’s fairly big; approx. 23 cm wide, 18 cm tall and 15 cm deep.You can use it as a 0.05-1.1 pf or 0.5-11 pf variable depending on which of the panel mounted 874 series connectors you used. The 874 series was developed in the late 1940’s. GR 874 connectors are hermaphrodites – they mate to themselves. Take a look at the cable sitting on top of the 1422. You can still buy a 1422-OD from IET Labs, Inc. if you have about $11,000 burning a hole in your pocket
