I had a 4040 lovely amp. Can I recomend Flashback Sales as a really good source of phono to din components. I got mine from there and they were excellent
Just to bring this thread to a conclusion, I thought I'd let you all know that I ended up with a Cyrus One, late model in black. £72 on eBay including a Lynwood IEC cable, and I'm very pleased with it. Its in fantastic condition, in original box and with manual.
Thanks for all the useful advice. Must get back to listening to it!
