        Complete stab in the dark

        well
        1.Its Japanese
        2.Its AF
        3.Its high gain

        Is there another thats working you can pull and test?

        This could be 100% wrong!

          Good stab OC

          It was a 2SC3135 substitute 2SC3330. Q507 was leaking DC to the sum out jack. All good now. Thanks for the assist.
