the answer
security torx, i think teddy bear hit the nail(torx screw) on the head. thats what it must be. do you know what size and where i can get one? at present iam working on fixing the lincoln cassette radio. it got a bad drive belt. but whats interesting is that to get at the drive belt you have to remove a plate thats held together with JIS screws, for which you need whats called a JISscrewdriver. whats a JIS screwdriver you say. its a screwdriver that looks very much like a regular phillips only its specially made for these particular screws found on this radio. ive found out that these screws are used on lots of japanese electronics. just thought id share this hope i didnt bore everyone. thanks again teddy bear. pmg
