TKD 2CP-2511 motorised potentiometer with remote control and controller board.
Bought new together from HiFi Collective 2 years ago to the day, but now surplus to requirements. Installation instructions available from HFC's website
Perfect working order. Some signs of desoldering and scratches from the grub screw on the shaft, and I've moved the IR sensor off board.
I'd like £100 inc UK postage for these.
