Boonton Radio Corporation

Boonton Radio Corporation was one of the most prestigious manufacturers of test equipment during the vacuum-tube era. It rivaled Hewlet-Packard in the care and precision of the designs. Unlike HP, Boonton sorta missed the solid-state revolution. Today, it is relatively difficult to obtain test equipment that works as well as the devices from Boonton. For a dip meter, one is better off to get a classic Model 59 Grid Dip Oscillator and find replacement tubes for it. Nothing matches the calibration accuracy and the signal strength of these classic units.
