  • Schematic wanted for FBT PROMAXX 15Sa daughter board

    Hi folks. I'm looking for the schematic for the daughter board for the FBT 15sa active sub.
    The amplifier section appears to be fine but for some reason the signal is not making it there.
    I don't have an oscilloscope right now and with the double sided board and on board processing i am getting a little lost.
    Can anyone help?

    The owner had tried to make the repair but made a mess with super glue and some random soldering.
    Also looks like C59 might be missing.
    Thanks.
    James

    Send them an email, they responded fairly quickly when I asked for a schematic.

      I repaired this amp.
      There was a tiny capacitor missing, it must have been knocked off o vibrated off the board. Can't remember the part now but it was fairly near the xlr input.
