    I subsequently joined in June and was absent since. Hello.

    To cut to the quick, I've been into cassettes since 1968 and
    am now trying to service my 35 cassette decks. This is to
    do with my very favourite deck, the Sony TC-153SD.
    Because I'm on a budget I bought 30 cheap belts off Ebay.
    Fitted the best compatible (very close) and although I've
    done everything possible, I am now getting mild Wow on
    playback.
    Is this because cheap belts cannot take the torque loaded
    upon them, and so they expand and contract in a sort of
    modulation over a matter of a second or so?

    I need a specific answer here I know, but someone does!
    I have a billion other issues but will spare you. Anyone who
    replies, no matter how, will be admired for their love of this.

    Thank you. Mark. London. x BBC(!)

    Yup, better belts. In my youth I repaired cassette, 8-track, and reel-to-reel players, and wow was usually belt problems.

    Remember the old carnival game expression "Close but no cigar!" (your expression reminds me of this (Fitted the best compatible (very close). :D

    Belts are a tricky item, too loose and they won't drive because of slippage, too tight, they cause too much friction (some motors have very little overhead in torque), couple all of the above with cheap
    construction and wow and flutter will abound! :(

    Cheap belts to get a toy to run is one thing, anything requiring precession speed control is quite another! :thumbsup:

    What everyone said. Good belts are usually precision ground and the thickness is very precise. Cheap belts are just rubber bands.

    I never heard about Mars but the one that comes to mine is PRB (projector recorder belt company).
