    I just received a Sony TA E1000ESD preamp, in a debt default. I realize this is quite old, Circa1992, but it has great sound. The motor for the volume control appears to be shot, the volume does work manually.
    Is there a way to check the motor?
    Can I replace the motor with one from another stereo (Kenwood)?
    I hate to toss this into the landfill, I am old school and still believe that quality things should be maintained and not trashed.
    Thanks in advance, (Newbie)

    Hello,

    You could try to measure the winding of the motor (you should measure some resistance).
    If you do not measure anything the coils are broken.
    You could replace it with a motor of about the same specs (voltage, current, resistance).

    Hello,

    I have a str-de135 from sony, that uses also a motor potmeter.
    The potmeter motor is driven by 5 Volts.
    I downloaded the manual from my str-de135 from this site:
    http://www.eserviceinfo.com/

    Here is the "volumepart" from my str-de135.

    I hope yours will look similar.
