Special features

Sonically balanced analog push-pull transistor amplifier with elegant, simple optics. Natural sound philosophy of Yamaha, best components and a real full-fledged 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 dots for information rounds off the positive overall visual impression.

report in "FonoForum" 11 / 1993

The user has purchased on 30.12.1993 in the shipping trade a device to DM 575, -.
The device is ok so far, but unfortunately the motor-operated input selector switch (source) has been causing contact problems for some time. Contact spray also does not help.
Repair is not worth it. Remedy: The input selector switch was bridged with wire bridges in the "CD" position, i.e. this input is constantly switched through.

My model is from 1992, in 2009 I changed the Input Select switch myself. The cost of the counter is about 80 €. In addition, the 2 relays for the speakers were switched on by mit, the original ones had considerable contact difficulties at low volumes. Subjectively, the AX 570 now sounds even better as new.

Also had problems with the input selector switch and the volume control. I completely disassembled both and cleaned them with cotton swabs and contact spray. Helped a lot, think like new. Now after a few years they are making problems again. Loudspeakers A&B are constantly on, I think the relay is stuck. Otherwise I am very satisfied.

If the switches are cleaned only with contact spray, you usually get problems again after a short time. You have to remove the contact spray from the switch / potentiometer again (e.g. with WL spray) otherwise it will continue to attack the contacts. Subsequently, the contacts are preserved, for example, with contact 61.
