Upon turning on, None of the signals show response. Until I fiddle around with the TL072 (353 substitution) in socket, it doesn't work. Finally taking an LFO to the input seems to work, though as I turn the rise knob 5 cents the signal dies. The fall knob shows no response. As I take the same signal and apply it to the trigger in, the LED stays on even if I take the signal out, until my fingers brush against the back of some of the pinouts of the 353 substitution. I already have a 114 board working entirely, trying to make a quad slope generator for a +/-15v system. The transistors are all 3904 and 3906, placed in reverse. I have the half of the board not yet wired up with a 353, as I wanted to compare the difference.
Any one have a clue whats going on? I looked for shorts, but came up empty.
