Well, I'll start by simply saying I have committed the cardinal sin when dealing with the technical side of Simmons gear....DON'T ASSUME ANYTHING IS AS IT IS DRAWN. Once again, the schematics simply don't match what is layed out on the original PCB. I'm kicking myself at the moment, need to alter a few things and work out if I can change the boards I have (ie cut a track or 2 and add some connections....those who have ever looked inside Simmons gear will know what I mean..lol)or get some more run.
Dave Simmons (if he ever visits and reads this stuff) I have come to the conclusion either;
1) Someone inside your old business was out to ruin you...or
2) You were paying for some engineering staff who were verging on incompetent!!
I have worked on enough of this gear to know just how bad some of the designs are. Don't get me wrong, the concepts and sound are second to none but the implementation of the hardware is truly bad in some cases. The SDS7 is probably the worst example. They are SO temperamental I can't believe they were built the way they were with the intention they would be carted around and gigged. You just have to look at them the wrong way and they stop working. The sockets for the cards are simply atrocious. God help anyone who has lost the little plastic card key in any slots...the board can misalign when plugged in or moved (vibration) and it WILL kill the board. The case design is not very rigid, all the cards use this non rigid case for support. Mis-handle the unit and you apply stress to all the PCB's leading to track/connection fractures. Simply wrong!!
Well now I've got that off my chest I'll go back to burying my boot up my own arse.
Be patient, I'll have a look at what I can do then get back to you.
