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.
Pictures[edit]

Reviews[edit]
- STEREO: very good **
- Stereoplay: top class II
- 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.
- 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&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.
