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.

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.

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.

  • Report in "FonoForum" 11 / 1993


Field report from 25.12.2009[edit]

  • The user bought a unit on 30.12.1993 by mail order at DM 575,-.
  • 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.

Repair is not worthwhile. Remedy: Input selector switch was bridged with wire jumpers in the "CD" position, i.e. this input is constantly switched through.

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.
