Repairing a Little Mark III Bass Amp
I recently received a defective Markbass Little Mark III bass amp in return for fixing some other audio equipment. According to its previous owner, the amp had all of a sudden started to blow the input fuse. Turns out, the amp had undergone repair before. The power amplifier transistors had been replaced, and blobs of solder and (seemingly corrosive) flux could be found across parts of the PCB. A quick continuity measurement shows that the transistors in the class AB power amplifier and the switch-mode power supply have failed. Other than that, no apparent damage was visible. Will a simple transistor replacement bring the amp back to life?
