My primary amp is a DRRI. I often connect this to the Musicman 210RP 100 by plugging a patch cable from DRRI input to MM input and point that across the stage for other band members to hear me. This weekend I did this and between sets noticed that the power light on the MM was out. I went up and looked at it and immediately noticed a burnt smell. The amp will not power up. Any ideas? This amp was immaculate but I hate to start throwing a bunch of money at it if it's a major repair.
