Those do sound familiar, especially if the hot, neutral, and ground
pins are round rather than spade-shaped.

Cords of this sort were used on some HP test gear, years ago, and
on some European electronics as well.

Take a look at http://www.volexpowercords.com/sea [...] i?match=40
and see if it's what you need.

Now, a cautionary note. There are two versions of this cord/plug.
They are physically identical, and differ only in the assignment of
the neutral and hot wires.

One version is as mandated by the (European?) CSA organization, and is
represented by Volex 17280. The other is the variety used by HP, and
is represented by Volex 17952. If you buy the latter, it comes with a
warning that it should be used only as a replacement cord for
equipment needing it, and should not be used for new designs.

You should check your Dolby gear's wiring, and see which of the two
pins on the socket is connected to the power switch or fuse. Use the
Volex cord which wires this pin to the line/hot prong on its plug.
This will ensure that the fuse/switch actually interrupt the mains
voltage rather than the neutral.

>Digikey or Mouser have nothing like it.

Mouser does carry both Volex cords... the Mouser part numbers are the
Volex number with a 686- prefix.

I just went though this exercise a couple of weeks ago, to get a
couple of flea-market HP test-equipment bargains up and running.

Are these round pins? If so, this was a standard cord that lots of people
(including Hewlett-Packard and some vacuum cleaner companies) used. Volex
makes replacement cords.
