Deluxe Octave Multiplexer schematic

Postby Pote Gui » 05 Aug 2017, 16:23

Hi folks!

I've just finished reverse engineered this pedal as I couldn't find a schematic one the net. It is not as clean as I wanted it to be at the beginning (started this off with a ruler, finished it without...), but it's better than nothing, right? I've planned to make a cleaner one using Kicad when I'll have time, but not for now.
It's on five pages because I couldn't manage to make it with less pages! I think it's quite usable anyway, but you'll tell me. Maybe someone here can make a one-page schematic?
Here we go!

And by the way, the (?) near the values are for those for which I'm not sure (hard to see the color and can't measure it unless unsoldered). The revision number of the board is 1325C. So it's a little bit different from the 1325D schematic Dirk posted the link some times ago.

You're right! Thanks for your help. I've checked my drawings and I've corrected them. I'll post them soon.

No, it used a CA3098 and was dated Jan/Feb 1978.

Ok, I've double-checked all the pages, and now it seems ok. If anyone find a mistake, please tell me and I'll correct them.
If appolo can assemble these five pages in one, that could be nice.
