Question about C320 2-Channel Amplifier
dc offset ok!.i then took it to repair shop to have bias set (i dont own an occiloscope) the repair guy used a steel screw driver & subsequently burnt out 8 transistors on the side of the driver board
...bias HVT. The DC-voltage for the developer bias is split between two colors ( magenta & yellow ) or ( cyan & black ). The AC voltage is supplied for all four colors and it's loss will be seen ...
DC bias cct nearby such as small transistors,resistors...If you are not familar with amplifier it better to find a tech as all amplifiers need a very precide repair technic , If the DC BIAS were wrong
