[Amps] conductive grease for roller inductor

[Ralph Young]

I have a Nye-Viking tuner with their home made roller inductor.   The roller
has seized up on the shaft that guides it along the inductor.   They used
some sort of conductive grease on the shaft and a few other places on the
inductor assembly to improve contact.   Does anyone have a source for a
conductive grease I can use on the roller once I get it all apart and freed
up?
