Bought a Yamaha A-1060 intergrated amp along with a pair of Klipsch Cornwalls back in 1983. 34 years ago. I still use the Cornwalls (rebuilt & upgraded) now. But the yamaha just recently took a dump. I took it to a local "stereo hospital", and they were bewildered by this "beast of an amp". They told me "they wouldn't even know where to start"??? The amp features an "X" design type high output power supply that know one seems to remember or understand? I also have a Yamaha A-1000 and a Yamaha A-1020, both are class A intergrated amps, but the Yamaha A-1060 makes them sound like it's step children on drugs.... The cornwalls are now being powered by a vintage PAS 3X tube preamp and a home made 8 watt tube amp. All's well, except, i keep praying that i will find someone in my town (tucson) that can fix my beloved A-1060 so that we may be together again to make beautiful music.
