Cambridge Audio Creek MM Phono Preamp internal module fits A series & Azur amps. This is the original internal moving magnet phono preamp module designed by Mike Creek for the first Cambridge Audio A1 model amplifier .It also fits subsequent models in the Cambridge A series: All the A1 mk2 and mk3 amps, the A2, A100, A4, A5 -, A500 and the C500 preamp separates. It can also be fitted to the Azur 540A and 640A amps, BUT ONLY THE FIRST version, not the V2 versions of the Azur, which had extra room networking circuits.All these amps were originally sold without a phono preamp, as at the time the audio world had abandoned record players in favour of CDs. Now, of course, vinyl is coming back in a big way and if you have a Cambridge A amp (which still hold their own well today) and you want to play records, then this is the way forward. No external boxes with annoying trailing wires and power supplies, you just remove the amp lid, plug the board into a pre-arranged spot of the main board of the amp and cut two small wire links to turn the AUX/PHONO input sockets into a dedicated turntable input. See the second photo, if your amp has a space like this, you are good to go.NOTE: The photo is of a typical module, the one you receive may have slightly different coloured components but will be an original CA module identical in spec and performance.FREE tracked and signed postage to UK, £7.99 tracked and signed postage to EU countries.
