[Robert A. Taylor]

I have the following for sale:

It has a 1.5 x 1.5 inch circuit board, factory wired, with a 2N2189 transistor oscillator circuit and ferrite tuning coil.  The complete assembly is less than 2 inches tall.  It is in the original box with mounting hardware but no schematic.  Being a single layer board, it would be easy to trace it out [12 parts].
