    Wenn ich meinen Beogram 4002 spiele, spielt er nur mit 33 U/min. Wenn ich eine Single abspiele (45 U/min), bewegt sich der Arm zum Anfang der Platte, aber die Geschwindigkeit bleibt 33 U/min. Auch die Feineinstellung bleibt bei 33 U/min eingeschaltet und springt nicht auf 45 U/min. Was kรถnnte die Ursache sein?

    Capacitors?

    1C20 and 1C21 points to C20 anc C21 on module 1.
    They are capacitors – not ICs.

    They are tantals. Tiny drop-like components.
    Make sure you get their polarity right or they may go bang.
