Can someone out there help me please?
I have a great old 70s solid state Sanyo briefcase type music centre which operates on batteries or mains. At the moment it works fine on batteries, but I would like to plug it in. I use it to play old vinyl records and because it’s portable, it’s great. The trouble is the old mains lead which has 3 pins in a row, disappeared years ago and is unavailable now, and I wanted to replace it with a ‘European’ computer type socket, so that I can plug it in again. But when I removed the deck to remove the 3 in a row socket, the 3 wires behind the socket are all red!!!

Obviously I don’t want to blow all the resistors by connecting the live and neutral the wrong way round. Does anybody know which wire is which or are they interchangeable? The middle pin is very slightly larger than the other two, so I presumed that this was the earth.

One of the end red wires (slightly thicker than the other two) goes to a voltage changer (110-220-240) the other end red wire goes into a little transformer, and the middle red wire disappears into the depths of the unit..

I would be grateful for any help please. I don’t know if the original mains 3 in a row plug was an early European plug or just an old Japanese plug?

Many thanks,
