Can anybody please help me identify a plug socket


I’ve recently acquired an Acorn Audio Comparator which is an old box that allows you to route between audio sources, amos and speakers in any configuration. The problem is that I can’t identify the input sockets on the back and can’t find the corresponding connector.

I think the mains socket is a Bulgin 3 pin but it’s the round metal sleeved sockets I’d like to know about. If anyone can help I’d be very grateful.

Honestly, I would not want that thing anywhere " in " my system. Why would I want to " dirty up " the signal of what I put together for " cleanliness.

I totally agree with you, KISS is best!
But I have an crazy idea that one day I want to take all the spare audio gears ( turntables, tuners, R2R, 8 track, cassette decks, cd/minidisc players, receivers, preamps and power amps and speakers) out of storage and set them up with a comparator in my basement...

Happy holidays
