    I've got the three screws on the rear panel removed
    which should let the chassis or cover slide out.

    It doesn't.

    What am I missing?

    Recall this is the reissue PAS3, the Series 2.

    3 screws on the faceplate ???? There is no screws on the original faceplate.
    Is this something different then dynaco pas3 as described in dynaco's manual ?

    a pas3 is opened via the 4 screws on the shortsides, then both bottom and top cover is ready to pry out.
