      ik heb de condensatoren vervangen + nog aantal andere condensatoren die verdacht waren, maar helaas geen resultaat, transistoren zijn ook niet temperatuur gevoelig!  het lijkt alsof het gedeelte van snelheid 45 geen spanning krijgt! ik kan de oorzaak niet traceren.

                Hallo Martin,

                are the ICs mentioned on the large printed circuit board or on printed circuit board no. 8

                        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 könnte die Ursache sein?

                        Grüße Fred

                          When I play my Beogram 4002, it only plays at 33 rpm. When I play a single (45 rpm), the arm goes to the beginning of the record, but the speed remains 33 rpm. The fine adjustment also remains on at 33 rpm and does not jump to 45 rpm. What could be the cause?

                          Greetings Fred
