<p>After getting the Drone Lab up and running, I find that the lpf_cut function isn't working. I went over the board front and back, reheating likely suspects. But it was only since this morning that I took the time to overlay front, back and silkscreen in Photoshop that I really (maybe) know where to look for a culprit. I'm attaching the file so that hopefully you can tell me if I'm on the right track.</p>
<p>Admittedly, I have not checked continuity. I'm a newbie with lots of soldering experience, but almost no troubleshooting or schematic reading experience.</p>
<p>The only things I was unsure/(or changed) about in the build were:</p>
<p>• I substituted a bright blue 5mm led in place of the stock red for the tremelo/clock pulse<br />
• I substituted a brighter Amber 5mm led in place of the stock red for the power indicator<br />
• I was unsure of which orientation to place the LM7809</p>
<p>The DL sounds great, but of course I want the whole package, and more!
