Yamaha R-9 need schematic
Hi; I just replaced outputs, drivers, .22 ohm resistors etc, in this R-9. There's still a problem with that channel (DC through spkrs) and protect relay won't fire until I disconnect the one of the collectors of either the output transistors. Or drivers. I have checked all the upper stage transistors, resistors, diodes and caps in the area that I can find. Something's still amiss. Does anyone have a schematic of this amp ? Any help appreciated, Rick |
