Customer Question
My Mobile AC portable...

My Mobile AC portable amp turns on OK and after a few minutes makes an awful racket. Sort of pulsating.

Technician's Assistant: What's the brand and model of your instrument?

Roland Mobile AC

Technician's Assistant: How long has this been going on with your Roland? What have you tried so far?

About 6 weeks or so. Can't use it basically. I did unhook speakers and put back together. Nothing makes a difference. Using AC adaptor
