Looking for General Radio banana plugs I came across this site. It provides some history on GR and to where it disappeared. I have their 1650A bridge and several other precision items, and from time to time these get used.
I never realized that some telegraph keys were designed for 110 V and 20 A, or that in the early days that GR made telegraph keys. GR precision instruments, Variacs, banana plugs, and precision components were the kind of items I associated with the company. In the early 1950s I used their noise generator as the basis for a random number generator.
