    Hi everyone,

    I recently acquired a Beogram CD 5500 player. After a few repairs to the DIN cable, which did not appear to be original (short circuit on the data wire), I also replaced infamous cap C2103. The player “works,” except for reading issues:

    The CD starts playing normally without any rubbing noise, the number of tracks is displayed, but the first tracks are choppy and skipping a lot. The tracking seems to try to reposition itself a lot. However, as soon as the middle of the CD is reached, there are no more reading issues.

    What are the different things to test, and especially how to check:

    • The press plate seems unlikely: it doesn’t rub against anything but seems to vibrate a lot; even when I manually re-center it to reduce vibrations,  problem persists Is the motor not spinning fast enough?
    • Is the optical block not following the movement well in the center of the CD?
    • The CDM block’s suspension? Where can I find replacements, or did anyone try to 3D print them?
    • The motor’s suspension?
    • Other ideas ?

     

    Thank you for your insights, and sorry for the automatic translation which may look a bit awkaward 🙂

    What brand and type of capacitor did you fit for C2103?
    Did you do any adjustments? – If not DON’T do any.

    Drive supports here.
    No, you cannot 3D-print these. There are more to them than meets the eye.

    Hi thanks, I’ll look into the replacement supports. I may try some 3D printed or home made solution as an experiment and will keep everybody posted.

    Regarding the cap C2103, I replaced with a random chinese one with same values I had laying around, I know there is a lot of discussion especially in a French forum about using an original one but thought it was a pedantic discussion … I kept the original and will refit it if ESR and capacitance values are still spot on.

     

    Edit : Cap c2103 it was tested : 37µF with ESR 6 Ohm so I guess it is toasted !

    a pedantic discussion …

    It’s not!
    The discussions didn’t come out of nothing.

    Get the proper parts.
