Hello,
I have built a circuit, that is composed of two of circuits seen in the circuit diagram; my problem is that one of these circuits works correctly and the other doesn't. The key difference is the voltages between the 383kohm resistor, on the side of the resistor with the black arrow the voltage is 2.96V for both circuits, but on the circuit that works the voltage on the other side of the resistor(red arrow) is 2.69V while on the circuit that doesn't work the voltage is 2.47V. Both circuits have the same components and are within the proper values of each other, I checked to see if there were any shorts but have not found any while also checking to ensure there are no cold solder joints. I would appreaciate any help on figuring out how get this thing working.
Thanks,
