  1. Hello,

    I need to power up an old Military Radar display unit build by Kelvin
    Hughes, code no RDS-A1, do any one know what was the supply voltage,
    frequency and power connector pinout?

    I suspect it may be 120Vac at 400Hz, but I am not sure. I also assume power
    input was going to the power switch, but I am not sure too. So any hint will
    be helpful at this point.

    Aircraft display, or ground display? There should be a tag (plate)
    indicating power requirements near the power input connector.
  3. Sadly, I can not find any tag (plate). What I suppose to be the power input
    is not even named, just a multipin military style connector. I figure it
    must be power input since the unit have no other connector (except video &
    sync). Two wires are route to the power switch, so they must be it, but no
    luck to power it from there, maybe the unit is also defective.
