Hi guys, I bought this unit used and suspect it took a whack by previous owner likely using it with an amplifier. When i decided to open it up to have a look and confirm jumper settings i noticed the stock light bulb/ fuse was cooked. I replaced it with another similar 12v bulb figuring this was the issue where the unit basically did nothing when powered on / tweaked adjustments etc. So, im assuming this thing took the juice and something else in there on the board may be shot. Anyone have any experience fixing one of these that suffered power hit ? Thx
 

You can use this to check values of the components and trace voltage paths to quicker locate the issue.

  • @ Hambones amps:
    Does anyone know if you can replace the 2290 in a galaxy dx 93t twin turbine with a 2sc2879 red dot? If so, what would have to be tuned?
  • @ ShadowDelaware:
    Hambones the entire amp section would have to be retuned, and the rf transformers re wrapped.
