That might be what I'm looking for. I have a Signal/One CX7A and
the power connector looks like a short Centronics printer connector.
At least I think that's the power connector.

What is it and where do I get one?

In addition, I need a couple powercords for the Heathkit SB-303/313.
This is a 3 conductor cord with round holes on the chassis side.

Anyone know what this is called, the part number or perhaps a common
instrument or appliance that used it?

I can't help with the Signal/One cord, but I'm pretty sure there
is a cord made by Belden that will fit the SB-303. My catalog shows
it as one of two possibilities: number 17280 or 17952. The cords
are the same except for the pinout: one has the line and neutral wires
reversed compared to the other. The ground connection is the same for
both. Either would work, but to be as safe as possible you should
check the 303's schematic and get the one that routes the line (hot)
wire to the fused/switched connection.

Your local friendly Belden distributor can get it for you (if you
still have one; our local jobber just went out of business), or
you can order it from Newark or somebody.
