Trouble seeing the saw wave on oscilloscope

Post by Sloz303 »

Hi there, I'm building my first xoxbox (from willzyx) It's going well so far, I've build the power and the beginning of the VCo but I'm stuck when it's get to the testing part with an oscilloscope.
I've test all the DC voltage, everything is good but nothing show up on the oscillo. Also i've never used the oscillo but I've red the manuel and everything I do seems good
Here is some pictures that you can see, the "croco" are connected to the oscillo and the "regular" is giving the power (from the power generator)
Ask iff you need any more info
Thanks
