Description

The M24 was an improved version of the 1959 M23 model. It was a professional quality recorder costing over £180 in the UK and many found their way into radio, television and recording studios. The transport was operated by solenoid “touch” controls and there were four mixable inputs; microphone, radio, turntable and line. Three motors and three heads were employed, and reels of up to to 9″ diameter could be used. The head assembly was removeable and interchangeable. Various versions were available: deck only, portable carry-case with amp and speaker or this de luxe version with two speakers.

I bought my M24 for AU$50 in 1987 from a chap who repaired Quad electrostatic speakers in a basement and after a few electronic repairs it worked beautifully. The bass and treble control plus the 6 watt power amp driving two high quality elliptical speakers gives a wonderfully warm sound.  The brakes have ceramic drums and the whole machine is a beautiful example of West German precision engineering.
