Hm. I scanned the original schematic, the schematic with the mods I?m trying to make, and the bit from the Jensen page. I had to add some things to the schematic as it only included the circuit that on the PCB, and none of the off board stuff. Hopefully I did it right (or close enough for you to understand). On the one with the mods, I tried to draw those as best as I can, but if anyone is confused about what?s there, please let me know and I?ll try to explain. As I?m new to DIY, I?m still trying to learn how to draw (and read) schematics. Basically, I?m trying to have a mic input, mic output (both XLR and TRS), and line input and line output. The input is supposed to be switchable from ?mic? to ?line.? I added a power LED. I also added a "power filter" because the unit was making this weird buzz and that's what was suggested to help it. Any suggestions about how to do this, or better ways to do it, etc, would be a really big help.
The only problem is that I don?t have a site to uploads the scans to. Is there a public site you guys use (yahoo briefcase or something?) or is anyone willing to upload these?
Thanks, David.
