General Description

The MC 1 was Telefunken's high-class cassette deck offering in the line of Midi-sized (30x30 cm basic area) Hifi components. In its features and basic concept, it is comparable to the RC 200: a two-motor deck, electronically controlled. In addition, it also provides the auto-rewind/auto-play functions known from the RC 300, but not the auto-start timer function.

As a part of the M 1 component system, it shares the unusual housing concept: the housing is made of an inner frame, and aluminium profiles attached to it make the 'outer skin'. This housing concept is similar to laboratory devices and in contrast to standard housing concepts of Hifi devices at that time, which were based on bended metal sheets. It gives the whole system a very worthy look, and Telefunken won an industry design award for it.

Common Failures

Similar to the RC 200, the MC 1 uses a two-motor drive with one motor for both reels. The motor'S rotations are transferred with a moving rubber wheel. The wheel's rubber hardenes over time, and dirt additionally reduces the friction (common with devices from smokers!). The result is a deck that plays and records without problems, but has trouble winding the tape. The effect is not as common as with the RC 200, but it is more difficult to fix, since the front cover has to be removed to gain access to the wheel.
