  • Marshall MG100FX Schematic Needed (not DFX - this amp does not have a TDA72xx)

    Hi,
    Desperately needing a schematic for a Marshall MG100FX, not a 100DFX. This amp uses a 2SC5200 and 2SA1943 complementary output pair vs the the TDA72xx found in the DFX. Have looked here and elsewhere on the web and all I find is MG100DFX. The PS/PA board I need schematic for is MG100FX-62-00.
    Thanks

        Watch out for D14 the 6.8 volt zeener diode.
        When that diode goes bad the amp will stay in standby, and no sound.
        (I have new output modules if you message me.)

          But, the fx is differen from the dfx model. This one has 2SC5200 & 2SA1943 output stage.
          Im struggling to find darn schematic. Even emailed Marshall

              Thanx G-one.
              The Mg100fx has no reverb tank. Instead a digital fx unit DSP.
