Hello everyone, I realize that there are similar threads active but to avoid confusion I thought I'd start a new one.
I have a willzyx x0xb0x kit that is nearly complete (just LEDs and LED resistors left to do). I just received my variable power supply and parts to make a soundcard scope so I can finally test what I have done.
The boards power supply works correctly.
I connected the variable power supply to ground and r90. On IC11 i get ~5.33V on pin 3 and ~3V on pin 5 and 7.
When I probe r105 with my soundcard scope I get nothing.
I checked pin 1 and 3 on the waveform switch. nothing.
I populated all the IC's and turned the machine on outputting a random pattern. nothing.
What else can I do to identify the problem?
Thanks in advance.
VCO, no output.

hi
have doubled checked all parts in the vco is in the right place and the right way?
sounds like one component could be broken as well.
theres a voltage chart in the make xox forum with dc values for you to refere with. see if you can narrow the fault down with that!
do you have the 12V in the vco working by the way?
