General Radio Company

The General Radio Company (GR) has produced many high quality instruments and measurement standards over the decades. Many GR instruments are still available from IET Labs. One of my favourites is the excellent 1615 capacitance bridge but the chances of finding one that somebody doesn't want are remote in the extreme.

A history of the company from 1915 to 1965 can be found below.

I don't have many GR items but they are still of interest and are in excellent condition. Please select an item from the sidebar for further details.
