The Rogers Junior started out life as a simple integrated mono amplifier in 1949 utilising PX4 output valves and having an output of 10 watts. It was available in kit form (£16. 17s) or factory built (£19. 10s). A set of layout and circuit diagrams plus parts list could also be purchased by the enthusiast for 7s. 6d. In 1952, Rogers released the Junior control unit (Mk I) for use with either their Junior-De-Luxe or Baby-De-Luxe power amplifiers. This simple, single ECC83 preamplifier had two inputs and a fixed low-pass filter. Shortly after it was updated (Mk. II) with a variable low-pass filter.

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.
