I am cleaning up the Front Control PCB (A4 Front Panel Board) on a TAS465. The Controls are a Simple Wiper that makes contact with carbon element pads on the PCB. Tek had some sort of original Black grease to lube the rotation of the Wipers.
What type of grease should I apply to the Carbon Element Pads to Lube the Wipers?
I have the following: GC Electronics Conductive Grease Silicon Grease (Food Grade) CRC Bulb & Connector Di-Electric Grease CRC 2-26 Multi-Purpose Precision Lubricant
