I have a marantz CP430. I had to replace the kit of 3 belts. Now, I have a new problem: that reads the audio cassettes at an accelerated speed. Does anyone have an idea of why this happens?
Hello Alessandro, if you have changed the three belts, it is very possible that the belt of the capstan, has been mounted on the edge of the motor pulley, which has a diameter may, therefore it will be faster the speed of the tape Re-disassemble and observe the location of this belt, verify that it has the same thickness as the original, also observe that the capstan are with their bushings well, clean well the surfaces where the belts work with Isopropyl alcohol If you have checked everything and do not find problems, you should adjust the speed of the motor, preferably with a 3 kHz cassette and a frequency meter or with an original, that you know the content I sent you the link to download the service manual I hope you can solve the problem Greetings Franco Dosil
Hola Alessandro, si le has cambiado las tres correas,es muy posible que la correa del capstan, se haya montado sobre el borde de la polea del motor, que tiene un diametro mayos, por lo tanto va a estar mas rapida la velocidad de la cinta Vuelve a desarmar y observa la ubicacion de esta correa, verifica que tenga el mismo espesor que la original, tambien observa que los capstan esten con sus bujes bien, limpia bien las superficies donde trabajan las correas con alcohol Isopropilico Si has revisado todo y no encuentras problemas, deberas ajustar la velocidad del motor, preferentemente con un cassette de 3 khz y un frecuencimetro o con un original, que conozcas el contenido Te envio el link para que descargues el manual de servicio espero que puedas resolver el problema Saludos Franco Dosil
