I have a nice 2500 MKII that sizzles and flickers when I turn it on. From reading up on it here at AK it sounds like bad contact inside the switch. I tried cleaning it with DeOxit and contact cleaner and it worked briefly but is back to sizzling again. I am going to attempt to open the switch and clean the contacts as others have done according to some other threads here but was wondering if anyone has any advice. I have attempted to clean a couple of switches before but a few times they were nearly impossible to reassemble without having four hands and ninja skills. Short of cleaning it, is there a replacement? I didn't find any mention of one here or anywhere else but the direct question was never asked. It is an Alps L-403 Power Switch. Thanks all!
