  • Ravensbourne 2 FM Tuner

    Rogers F.M. Tuner Provisional details were available at the 1968 Audio Fair of a new FM tuner unit displayed by Rogers Developments which they call the Ravensbourne 2.
    Although designed for use with the Ravensbourne stereo amplifier, it is suitable for many other amplifiers.

    The Ravensbourne 2 is an example of a product designed primarily for export, but which is recommended for use in this country where reception conditions are challenging. It has high sensitivity (3,1 µV for full limiting) and high selectivity, but adequate bandwidth for stereo reception.

    Three FETs are featured in a four-gang front end followed by six silicon and one germanium type. An optional decoder contains a further seven silicon transistors. Audio output is 150mV r.m.s. average (mono) and 200mV r.m.s. average (stereo).

    Four different prices are quoted for the tuner according to whether it is supplied with or without decoder and case. The top price for a complete stereo model with case is £63 10s.

    This was followed by a more sensitive version the Ravensbourne 2 FET tuner, Series II.
