Diode identification

    I have recently started working for a repair company. I have come
    across a diode that I cannot identify. I have talked to the others in
    the company (all 2 of them), and they can't identify it either.

    It looks like a small axial leaded sugar cube with a small red or
    green dot to mark the Cathode. There are no other markings on it.

    Any help would be greatly appreciated.

    Thanks,
    Ken

    that is why you need the service manual.

    Makes me wonder if this might be one of the little potted selenium
    diodes that were used in grid bias circuits of '60s audio tube amps.
    If it's one of those, it can just be replaced by almost any silicon
    diode, 1N4007 or better.
