Hello all,

I'm restoring a 50s vintage EICO 720 transmitter. I'm in need of a 50 k
potentiometer rated at 4 watts (or above) that is NOT wirewound.

The old part looks like a thin ribbon-like piece of resisitive material bent
into a circle and placed inside the pot case. The spring loaded center
contact appears to be in good shape, but the ribbon is fractured
(microscopically) in two locations along its length.

I have been unable to find a replacement for this part at any of the large
parts supply houses.

Does anyone know of a source?

Regards,
Peter Barbella
