Remarks

  • The Luxman Laboratory Reference series made its debut in 1976.
  • Highlights were the first Real Time Processed DC amplifier and the first synthesizer tuner.
  • Other components of the Laboratory Reference Series included the 5M-21 power amplifier, the 5G-12 graphic equalizer, the 5F-70 parametric tone control, and the 5E-24 LED level meter unit.
  • In 1977 and 1978 the Luxman Laboratory Reference Series was extended by the following units: The 5L-15 integrated amplifier, the 5M-20 power amplifier without VU meter as well as a cheaper tuner, the 5T-10 and the cassette tape deck 5K-50. The latter was probably purchased from a third party manufacturer.
  • The functionality, performance and innovative design made the series unique and distinctive.
  • Special features were:
    • World's first DC amplifier and synthesizer tuner.
    • Computer controlled cassette deck

Stackable components (the 4 device feet had corresponding recesses with the device standing underneath)
