Old Radar Display, need info

[Jacques St-Pierre]

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.

Bye

Jacques

Aircraft display, or ground display? There should be a tag (plate)
indicating power requirements near the power input connector.

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.
