    I'm trying to find inductor replacements for a vintage power supply. Would
    be grateful if you could point me to a supplier for replacements. These
    are the main power inductors in a H740 PSU in a PDP-8/M.

    - Type: potted, square rectangular box
    - Terminals: screw-on, 1.75" apart
    - Dimensions: L2.5" x W1.25" x H1.8"
    - Requirements:
    1. 100uH/20A or better
    markings on inductor:
    1610717 BOURNS (1N 0023)

    2. 200uH/10A or better
    markings on inductor:
    1611031 BOURNS (1N 0026)

    What is wrong with the inductors in the power supply you have?

    The original inductors are "whining" very loudly. My guess is that the
    core has been shaken loose internally due to its age..
