  • Annotazioni
  • The Rogers Ravensbourne Stereo was a significant transistorised amplifier introduced in 1967 by Rogers Developments.

    Key features include:

    • First transistor amplifier from Rogers, offering 25W per channel
    • Used modern silicon transistors instead of tubes
    • Priced at £64, between the HG88 tube amp (£46) and Master pre/power (£90)
    • Employed 2N3055 transistors, like other high-end amps of the era
    • Claimed low distortion and noise, excellent transient response
    • Connector for auxiliary external PreAmp for Tape Head / Microphone / 2nd Pick-up.

    It was only produced in one version, unlike the later Ravensbrook model

    Updated in 1973 with DIN speaker connectors and a higher 35W rating. Details here.

    The Ravensbourne represented Rogers' transition to transistor technology, offering increased power and performance over their tube designs in a similarly styled package. Its transformer-coupled output stage was an innovative approach, though it introduced some complexity in setup and maintenance.

    Only one channel is listed in the transistor lineup.
