one of the greatest amplifiers ever made the vast resources of such a large corporation like yamaha . if you have a chance to buy a used one and have it rebuilt to spec youll have a smile on your face for a long time. its not just from the golden era of audio, its from that brief platinum era.



re: M-70

I was stationed in okinawa japan in 1982 and bought the M70, C70 and T70 along with other pieces. My wife said "you better get what you want now because we are not paying the stateside prices" and so I did.
