Can anyone identify this psu connector ?

Thanks for the replies folks, I believe you're right. I've serviced two separate but very similar looking components from this manufacturer - a line level pre-amp and a phono stage, each with an outboard psu. The owner of them both now wants me to build an alternative psu for the line level unit. He brought the original psu over for me to photograph and that's what you can see above. I remembered that it had a screw connection but I've checked my original notes and it turns out that it actually had a push-fit plug and the phono unit a screw-fit one, presumably to avoid mixing them up (the psus are very different inside).
