I have a problem with one of my Mackie SRM 450 v2's where the high frequency driver intermittenly cuts out. It is, however mostly out now. The diaphram is good. I have pulled the amp and verified when failing there is no output to the HF driver. I have looked and tapped around the board looking for loose connections and bad solder joints but have found none. Does anyone have any ideas? I do not have a schematic for the V2 and it is vastly different from the V1. I don't think I can troubleshoot this problem without a schematic so if someone could let me know where I can download one I would much appreciate it. I am an ET with equipment so I would like to take a crack at it before taking it in for repair.

Thanks,

-Steve
