Powered monitor issue - flutter

One of my Fostex powered monitors has developed a very low amplitude 'flutter/motor boat' sound. I've switched the power to a different surge protector. It isn't coming from the input because it still does it without it connected. Built-in amp issue obviously? Going to get worse? Should I start looking for new ones I wonder?
