I built a Electrovibe based on the provided schematic on the page and have not been able to get it to work as it should. The PCB and schematic are almost identical to the schematic but I'm running into an issue where I'm not able to get a signal and am instead getting noises and random other fuzz. Granted the main difference between mine and the original are the use of a single vactrol replacing the four LDRs and the bulb as well as the LFO, but in theory should work the same. I even used a breadboard to rebuild it and have ran into the same issue. This time, after removing the the wires connecting to C6, C10, and C12, I was able to get a clean signal through, but of course no modulation effect. My own clue is having something to do with the lower section of the circuit that isn't working, but the fact that both a PCB that follows almost exactly what the schematic shows and a breadboard having the same issue has me stumped. Any suggestions or has anyone encountered this issue? Included is my schematic, with the ports 4 and 3 connected to what's supposed to be the single LDR, but everything else should still be the same
