I got this thing working, except for the dreaded threshold control. I was searching this thread, and it seems to me the voltages coming off the opamp by the threshold control (IC3) are out of whack. My voltages are:
IC3a Out: 0.1v
IC3a In - : 0.1v
IC3a In +: 7.3v
IC3b Out: 13.5v
IC3b In - : 6.8v
IC3b In +: 7.4v
Power and ground checks out fine. I have the threshold pot and the gate transistor replaced with leads to a breadboard to swap components around to try to get this working. It seems like fiddling with these does nothing. What's going on here?
