I have been having issues with my Caiman. Over the last few months it has been developing a crackling distortion problem. It varies in intensity depending on the material but at its worst it is unlistenable. The distortion is present on all inputs now whereas originally it existed solely on input #1. The distortion is similar to that which can be heard from an over-saturated recording on tape, any ideas? The unit was factory fitted with a Gator board by Stan before it left the factory but apart from this it is a standard, unmodified unit. I do not have the original board to test whether the Gator board is at fault, as has has been suggested by several members.
