<p class="MsoNormal">I would imagine what’s indicated on your power supply must be correct. I also found another image online of a power supply and it had the same pinout. Perhaps the schematic has an error or perhaps there was another version. I should be
able to open up the theremin and see if pins 2 and 3 are both connected to ground.<o:p></o:p></p>

<p class="MsoNormal">Interesting because the pinout shown on your power supply is different than indicated in the schematic in the manual on fdiskc. There pin 1 is connected to power and pin 2&3 are connected to ground. I wonder if that means there were different
versions?<o:p></o:p></p>
