    Ashdown Mag 600 schematic needed

    Hey guys!
    I'm not having good luck getting a copy of this schematic from ashdown. I've found almost every other ashdown amp schematic but not the mag600.
    Any help would be greatly appreciated!!!!!
    Thanks Tim

    Just a quick heads up if any one else has the same issue with finding the schematic. the schematic labeled "abm output board"--drawing # acd033 can be used. Its about 99% accurate. All i've noticed so far that is different is that one of the signal input connector pins is unused.

    Can someone please re-post the schematics. They're gone from the website now.

    Thanks, thats very useful when the mosparts flame out. This amp like some other Ashdowns of similar design suffer from poor thermal feedback. The NTC disc is only coupled by being pressed against the heatsink in some white thermal conductive goo. Over time it drys out and the themal coupling looses effectiveness. happened here. I have made a positive pressure clip to firmly clamp the NTC and bias transistor ;sometimes also there; and that prevents the decoupling of the thermal control. Anyway Thanks again
