Hi, I have A CA A1 Mk 3 amp for sale, very good order and working well, these are a classic UK hifi model, thousands sold and still in use. Actually I also have the original A1 Mk1 designed by Mike Creek, too, and some other amps and receivers by NAD, Pioneer, Kenwood etc, plus speakers, CD players and turntables (I am a bit of a hifi fixer and hoarder).
