I did a post mortem on the 470 ohm failing pot and it appears the resistive carbon track has fractured in the middle. The material looks to be graphite bonded to a paxolin like material. I have nothing to lose in attempting some sort of repair with a conductive filler material of some kind as getting a replacement slider pot is going to be a challenge.
