• Bemerkung

• 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.
