Recived my replacement output board great service from the full compass staff. But after installing only the side speakers worked so I checked the power to the amplifer board and no voltage there, removed the the power supply board (six screws on the bottom of amp) and see two of the SMT resisters are burned so here's another order i found that the price of the power supply has gone up by $10.00, but such is life. One must invest in there future

And I wonder why I can't order Part # 35-00-0544 The audio output board. It is a poor design based on a $3.00 Chip . Power is fed direct from the A.C. Line with no Breaker or fuse.How can a company associated with Yamaha do this!
