[QUOTE="marantz123, post: 1138511, member: 16849"] Best of luck finding an exact replacement. That pot can probably be repaired if the carbon track&wiper is still intact... with a bit of work and know-how. The broken wafer could be glued onto a substrate backing (eg. a piece of blank paxolin or fibreglass pcb). To repair the connection (conductivity) from the carbon track broken edge to the rivet terminal one could use the conductive glue used to glue/connect car demister contacts to the element on the windscreen/back glass. The spindle can be replaced from a scrapped pot, again with a bit of ingenuity. If its a standard linear pot then a complete replacement could be retro-fitted. If a log taper, then a fake log-law circuit used on a linear taper pot could work well enough if a suitable log taper isn't available. (Linear taper pots are said to be of better manufacturing quality as compared to log taper pots hence a fake log cct on a linear pot can work well). [/QUOTE]
