I would start by examining all the capacitors. Some might even go so far as to just blanket replace all the electrolytic capacitors on any vintage gear. I'm sure there are plenty of results in the archive if you search for capacitor and most will be talking about replacing faulty aging capacitors. It would also help us to help you if you could post some pictures of the circuit boards. We could help you diagnose the board to find out the source of the problem. Chances are its either failing capacitors or a failing power supply. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
