SOLD  5/24/12

This Yamaha MX-600 power amp has had complete service including cleaning everything inside and out, including both input attenuators. We also disassembled and re-soldered both banks of speaker output binding posts and input jacks. Upon reassembly we also verified the face plate, attenuator alignment. All illumination lamps / bulbs verified for operation. All 8 Output transistors individually tested. Transistors mounted with silicone sheets so no need to worry about heat sink compound hardening in the future. This amp has had the RCA inputs 'upgraded' in the past by a 'custom hi-fi' shop, however they had 'inverted' the L&R. We corrected that on the upgraded 24k gold RCA input connectors. Both inputs tested and both side produces clean and even sine waves into static 8 & 4 ohm loads! No power supply hum of any kind. It's dead silent! All functions test fine.  Following restoration procedures, the unit was.....
