| br>I just finished buidling this from a kit
everything seems to be working (clock in is ok, steps advance, reset button and inout work, step button works)
Except I don't get any CV out, it is always a fixed voltage...
Movinge the "scale" knob doesn't help, nothing happens...
I have double checked every solder joint and they all look ok, no cold joints, apparenlty no errors in component polarity or whaterer...
What should I check for defects?
