i recently built the cgs master divider, and am having trouble isolating a couple of problems (possibly one problem with two symptoms).
everything works fine, except: 2A stays at 5v, and 2C stays at 0v. the other "2" divisions work fine.
i swapped out the transistors related to those outputs, as well as swapping the 4070, no change. continuity has been checked from the output at the jack/led to the chips. the leds light/jacks work when plugged into other outputs.
i'd be appreciative of any suggestions for further investigation, and welcome the opportunity to learn from whatever mistake i might have made (or from the remote chance that a part may be defective).
thanks,
matthew
