the output on my dx7 has been flaky since I purchased it 1 1/2 years ago. I'd like to get this fixed, does anyone know if you can still find parts for such a repair and who in the pittsburgh area might be able to perform it? it looks as though there's just a few soldering points, but I want to make sure I can find the correct jack and it's done properly. any help would be greatly appreciated. thanks DJ

This the circuit diagram for the DX-7. Maybe that will help you to identify the output jack.

Try calling Yamaha at 714.522.9000. They can refer you to a servicer.
