Howdy. I am troubleshooting the Cobbler Preamp and I think the voltages are way off. the input voltage is 9.44 and drops to 9.41 after the d100 diode… ok so far (I think) Followed by R100 a current limiting resistor in series. There is no continuity between the negative d100 diode and the r100 resistor…… I physically bridge the resistor leg to the the Diode and now only get 3.4 volts to pin 1 of the ic100 charge pump…. Something must be wrong? Any help would be great full!
