Not sure who made these motorized pots. But they look like dual trace (stereo) 50K pots and the motor starts to run slowly on 3VDC - runs fast on 6VDC. Taper appears to be non linear. Thanks to a purchaser - He added the schematic included in the pictures. Shaft is 0.235" diameter, and sticks out of the bushing 0.715". Stepped portion of the shaft is 0.475" long. Please feel free to return items that do not meet your needs within the 30 day period, we only want satisfied customers! Thanks and God bless!
