Motor worm gear in the volume control of a preamp was making grinding noise so in my infinite wisdom I put the gloves on and decided to see what the issue is.
Cheap Shinesse Soundwell motorized pot unit is used as a voltage reference (just one section ) for CPU controlled sets of CMOS switched resistors.
I took it apart and plastic gears disintegrated on touch. Specs of the motor RPM 3300 6V Max , pot value is 10k .
I see Mouser has a similar looking pot with 4.5V motor and 10k linear pot.
What are the chances that substitute will work ?
