Unfortunately that was in the Seventies when I was working for a radio/tv firm and got a stupidly good deal on a Quad 33/404 and the speakers. Made the mistake of selling the system to a friend (who still has it) and bought a huge Rotel RA1412 amp and a pair of Kef 104Ab’s which I later changed to 105’s.
Still got the amp and speakers 40+ years later (and 2 pairs of 104Ab’s in the loft I picked up as “spares” just in case!).
There’s a couple of RA1412’s on eBay, each going for over £1200! that’s almost 4x what I paid for mine in 1979 🙂
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
