Analog Tuner
1981
DEM 215,-
The MT 2 was part of Telefunken's M 2 Midi-sized, low cost component system. The M 2 was by far the cheapest component system Telefunken sold at that time. Its principle was to offer a good price-to-performance ratio, by leaving out non-essential 'luxury' features. Consequently, the MT 2 is just a 'simple' analog tuner, but with a beautiful backlighted dial that is larger than e.g. the dial of the much larger RT 100, plus a dual-gate MOS frontend section that was state-of-the-art at that time.

None known, except for the usual burned-out light bulbs. The MT 2 uses four fuse-shaped bulbs that are located entirely inside the closed light box. This gives the MT 2's dial its good appearance, however it is necessary to remove the front cover and scale mask to get access to the bulbs.
