I just bought this a couple of days ago from Richer Sounds.
Cambridge Azur 640A Amplifier, 65 watts per channel into 8 ohms and five inputs plus two tape loops.
Absolute bargain at £150.00 and I can't believe how fresh things sound now, it's like having removed a pair of curtains from over the speakers and the bass is tight.
It replaced an old Kenwood amp.
It is the Mk 1 version and there's a Mk 2 out now so it's discontinued, but I'm well happy with it
