== Erfahrungsbericht vom 25.12.2009 ==
 
−
Der Anwender hat am 30.12.1993 im Versandhandel ein Gerät zu DM 575,- gekauft.
 
−
Gerät soweit okay, aber leider macht der motorbetriebene Eingangswahlschalter (Source) schon seit einiger Zeit Kontaktprobleme. Kontaktspray hilft auch nicht weiter.
 
−
Reparatur lohnt nicht. Abhilfe: Eingangswahlschalter wurde in der Stellung "CD" mit Drahtbrücken gebrückt, d. h. dieser Eingang ist konstant durchgeschaltet.
 
  
−
Mein Modell ist aus 1992, 2009 habe ich den Input Select Schalter selber getauscht. Kosten Schalter ca.80 €. Zusätzlich wurden von mit die 2 Relais für die Lautsprecher Einschaltung getauscht, die Orginalen hatten erhebliche Kontaktschwierigkeiten bei kleinen Lautstärken. Subjektiv klingt der AX 570 jetzt noch besser wie neu.

* Device so far okay, but unfortunately the motor-driven input selector switch (source) has been causing contact problems for some time. Contact spray does not help either.

My model is from 1992, in 2009 I replaced the input select switch myself. Cost switch ca.80 €. In addition, I replaced the 2 relays for the loudspeaker activation, the original ones had considerable contact problems at low volumes. Subjectively, the AX 570 now sounds even better than new.
 +
 
 +
* Also had problems with the input selector switch and the volume pot. Took them both completely apart and cleaned them with a wattage stick and contact spray. Helped a lot, think like new. Now after a few years they are giving me problems again. Loudspeaker suctions A&amp;B are on all the time, I think the relay is stuck. Other than that I am very satisfied.

 +
If you only clean the switches with contact spray you usually get problems again after a short time. You have to remove the contact spray from the switch/pot (e.g. with WL-spray), otherwise it will attack the contacts further. Afterwards the contacts are preserved e.g. with contact 61.

Hatte auch Probleme mit dem Eingangswahlschalter und dem Lautstaerkepoti. Habe beide komplett zerlegt und mit Wattestaebchen und Kontaktspray gereinigt. Hat sehr viel geholfen, denke so wie neu. Jetzt nach einigen Jahren machen die wieder Probleme. Lautsprecherasugaenge A&B sind staendig an, ich denke das Relais klemmt. Ansonsten bin ich sehr zufrieden.

Weden die Schalter lediglich mit Kontaktspray gereinigt bekommt man i.d.R. nach kurzer Zeit wieder Probleme. Man muß das Kontaktspray wieder aus dem Schalter/Poti entfernen (z.B. mit WL-Spray) da es sonst die Kontakte weiter angreift. Anschließend werden die Kontakte z.B. mit Kontakt 61 konserviert.

Notes[edit]




Sonically balanced analog push-pull transistor amplifier with elegant, simple look. Natural sound philosophy of Yamaha, best components and still a proper full phono preamp MM and MC.

The design of the Yamaha AX-570 is characterized by the round selection switches and stands out pleasantly from the very technical-looking variants. The metal housing is solidly constructed and the materials look very appealing. The discreet use of small light points for information round off the positive overall optical impression.
