Alesis DMPRO repair

Alesis DMpro

 This unit had no outputs when it came to our shop. The issue with these Alesis drum machines is that the filter capacitors fail, and some of the other electrolytics. I believe it is because they are really small.... that's why I always recap the whole unit with higher voltage capacitors, and if they are a little bigger I move them a little bit as shown in the picture below. A small bit of hot glue holds them in place, and they last much longer than the original ones.
