    What would cause a hum on the upper limits of this organ's manuals and it there a simple fix?

    Thanks!

    Could be a power supply filter capacitor.
    More info would help.
    Hum with or without tabs on? Which tabs?
    Is it expressible?

    You will probably have to take some voltage measurements.
    Do you have the service manual?
