CMT 20/200/100 series

Working prototypes were even shown at the Hannover industrial trade fair in 1963. They used bipolar transistors in a patented radio-frequency circuit, and offered SCHOEPS' first transformerless output circuit. The CMT 20 was then followed by the CMT 200 with increased output levels (via the original “SCHOEPS output circuit” invented by Küsters), and the CMT 100 for parallel powering. In this group of models the amplifiers were each tuned precisely to their individual capsules; thus the capsules weren’t interchangeable.
