• Notes

• The Marshall 9200 and 9100 were valve power amplifiers introduced by Marshall in 1993 as part of their rack technology line.

  These amplifiers were designed as dual monoblocs, offering a unique stereo configuration in a single unit.

  Key Features

  • Dual Monobloc Design: Both models featured a dual monobloc configuration, which was considered a notable feature at the time
  • Stereo Operation: The amplifiers were designed for stereo use, with each channel operating independently
  • Valve Technology: These amplifiers utilised vacuum tube (valve) technology, continuing Marshall's tradition of tube-based amplifiers

  9200 Model​ Specifications

  • Power output: 2 x 100 watts
  • Tube configuration: 8 x 5881 power tubes
  • Dual monobloc design with independent channels
  • Each channel features:
    • Power switch
    • Standby switch
    • Voice toggle switch
    • Presence control
    • Gain control
  • Gold front panel with recessed controls
  • Removable top half with window for valve visibility and access
  • Remote voicing switching capability
  • Output impedance options: 16 ohm or 8 ohm
  • Rack-mountable: 19" 3U x 331mm deep
  • Weight: Approximately 74 pounds (33.6 kg)

  Despite their powerful output and high-quality sound, the substantial weight of these units, particularly the 9200, was noted as a potential drawback.
  Over time, Marshall made changes to these models. At some point after their introduction, they switched from the original tube configuration to using EL34 tubes in a 100/100-watt configuration for the 9200 and a 50/50-watt configuration for the 9100

  The Marshall 9200 and 9100 represented Marshall's foray into high-powered, rack-mountable tube amplifiers, offering guitarists a combination of traditional valve tone and modern stereo capabilities in a professional-grade package.

  Note: Output tube types 5881 or EL34 should not be mixed.
