    Hello;

    I have a Sony SLV-750HF with erratic capstan speed.
    Looks very much like capstan assy. because it responds
    to tapping on the PCB right under the cap motor only.
    I cleaned and resoldered connectors in that area, but little change.

    Can anyone give me a Sony part no# for that beast ?
    Thanks,

    Rick

    I assume you've ruled out a worn bearing causing it to rub against the
    coils?

    Bearing kit from MCM, Sony part # X-2625-356-2. Price about $6-7. The only
    problem they have a $25 minimum. Try www.iglou.com/studiosound/ . They don't
    have a minimum order.

    How does one verify a bad capstan
    bearing ?

    Should there be "play" in the capstan shaft ?

    Thanks again,
    Rick

    With that chassis, when the bearing goes bad you will hear a faint
    "whish-whish" sound as the capstan rotates. It is dragging on the motor
    coils. Another symptom, it will be playing & will suddenly go into "pause".
    If you let it go too long, the motor windings will be damaged beyond repair
    & will require the entire motor be replaced.
