Hi Joe,


again, a very interesting application of a simple part.

Here is another one using a neon as a controlled switch.  Before we have digital circuits with battery back-up rams eproms flash and other stuff, it was hard to store an analog value over a long periode.

This was needed, if you use a remote control for a radio or tv and not want to use a motor-potentiometer.

here a circuit a draw as good as I remember it from Grundig. I ask Mr. Knoll, if he find an original schematic.
