Hi I have just joined the forum and new to this . I am trying to repair my Yamaha AX 700 . I have the left channel working . I have ran comparisons against the right ch. which keeps blowing the outputs , driver and predriver transistors. I have noticed that the dc . voltages on the emitters and base of the working channel as well as the blown channel pulses.The collectors are stable at -64 and +64 . any one has any suggestions
