I played a gig Saturday and had to use my PF350 (never used it before for a gig but use it all the time for practicing by myself) because my SVT3 Pro was out getting biased. Played perfectly for a three song sound check, left the amp turned on but not plugged in to my bass. The first song of the gig my 350 started cutting out intermittently (every 5 to 15 seconds for a note or two) and come back in. I didn't have a backup close and played the rest of the gig that way, it never stopped cutting out. I'm at a loss for finding if this happened to anyone else and I've searched a lot of threads on TB and Google. Anyone have a similar problem and where do I need to look. I visually inspected the PCB and everything looks good, no burn marks, no burnt smell or ozone smell, at a loss for what it could be. Has anyone run into similar problems? Thanx!
