      I am not too sure what that was all about.

      Anyway, I believe the BX4210 output section is a Class D design.

      If so, here is the schematic for the amplifier.

        A bit more descriptive text would be useful here rather than a tube video i.e. what the fault is and what you are trying to achieve.

        Tracing back the connections with a continuity tester should give you a rough idea.

        My guess of what that 6 pin connector carries is based on the BVT 4500h.

        Plus and minus 15v supply and power supply ground. (Pins 1,3 & 2)
        Output from pre-amp post master vol and audio ground.(Pins 4 & 5 )
        Limit L.E.D. drive from power amp. (Pin 6)

        Hopefully someone has had hands on experience with this and or the correct diagram.
