  • Notes
  • Marconi Scientific Unit No. 12  Super Sensitive Amplifier

    The Unit System No. 12 consisted of  three high frequency amplifiers, one detector, and one note Magnifier in a single cabinet.

    The Unit No. 12 Super Sensitive Amplifier is considerably more efficient than the similar Unit No. 11 since it employs two distinct methods of intervalve coupling, one of which delivers extraordinary responsiveness on Wireless Telephone wavelengths.
