Minor issue with SDS8
2013-09-18 by <ptmetcalf@...>
I did a quick visual inspection of the board and found nothing obvious like burned out components. Is this a common issue with the SDS8 as it gets older? I do have a factory schematic and do have some basic electronics knowledge and can solder well. I'm 3 for 4 on repairing older Simmons equipment (2 SDS7 repairs successful, a Hihat card conversion successful, but one failure....my SDS9, which I gave up on and sold off for parts or repair.)
I guess what I'm asking is where to start looking for issues? Is it in the noise generation circuit, the 3372 chip, a common diode, cap, transistor or resister in a certain circuit, or in the "latch" circuit I should be checking?
To me it sounds like a circuit is "stuck" or "cross talking" when it does this, which is all the time.
