Re: Pioneer VSX-520-K Protection problem
[QUOTE=rievax_60;770457]If the input differential transistor pairs lose Emitter current, the amplifier outputs will go to a high positive voltage. There is a 12v rail that is common to all channels.[/QUO
were is the differential transistors pairs? i attached here service manual ..can you explain where its coming there is no 12volt rails as per schematic
