Rogers RD Junior mono control unit and power amplifier (1952-1961) | |
In 1954, Rogers released the Mk. III pre-amplifier and at the same time, a matching power amplifier. The new control unit boasted more inputs (tape and radio), variable low and high-pass filters and a 4-position record equalisation switch. The power amplifier had two EL84s in push-pull and could deliver 8 watts at 0.12% distortion and 14 watts peak. A Mk.IV control unit was released in 1957 and a stereo control unit (Mk. 1 stereo) was available in 1958, followed by the Mk. II Stereo (1960) and Mk. III Stereo (1961). The Junior Stereo power amplifier was available from 1960 to 1964 and cost £28. 10s. On today's market, the mono control units are not very much sought after and have (by today's standards) very dated sound. The mono power amplifier may reach prices of up to £250 if in excellent condition, the stereo version possibly double that figure and more with a matching stereo peramplifier.
