I have a KX1200.1 amp, and I've had some technical difficulties and need to get the top off of it (the actual top off of the amp to check out the internal wiring). The amp uses allen wrenches and screws, and as sad as it sounds, one of the screws is so worn down (inside) that the wrench won't get it unscrewed. Sounds pathetic, but I'm not one to be good with tools. How else can I get one of these screws out when it's too dull for the actual wrench?
get a dremel tool (40 bucks, wal-mart) and use the metal cutting blade to cut a 1/16" deep groove in the top of the screw. then use a flat head screwdriver to unscrew the screw
