Reviews
The unit was tested in "Audio" magazine January 1982 (with 3 other amplifiers) and scored best based on Phono-MM input source. Only for Phono MovingCoil input source the Pioneer A-6 was slightly better.
In the Funkschau 3/1981 a report about the amplifier and the technology of the X power supply was published by the then Yamaha service manager Gernot Osburg.
This Yamaha model was affected by the problem of the bursting of a Rifa interference suppression capacitor in the power supply and was modified by Yamaha free of charge in a recall campaign in 2007 (now Wima interference suppression capacitor). On my device the damage occurred only in 2018, so 37 years after purchase: Yamaha nevertheless took over the free repair ! Here the customer is still highly respected !
