Mackie M1400 poweramp problem
Hi all. I had a shorted driver stage (MJE15032/33) in one of the
channels which resulted a lot of open resistors in the output stage, Some components in the clip-detector circuit blew too. After replacing all the broken stuff, the channel operates, but with high frequency ringing superimposed on the fundamental sinewave. Does anyone have a specific tip for this failure? Some of the compensation capacitors gone bad? Thanks a lot for any advice! Regards Steve |
