Thanks for reporting.moogchild_synthdrome wrote:I've found a mistake in the Extra9 board and the schematics. I haven't seen it commented here, so I'm mentioning it just in case. Capacitor C75 is reversed both in the schematics and in the silkprinting on the board. Positive pole is connected to ground while negative goes to the +15V line, and it has to be just the opposite. Take care while soldering this part, just turn it upside down. I'm sure most people might have it installed the wrong way.

What's the consequence of the wrong orientation of this cap?
