  Hey community, I started building my Nava 909 and successfully finished the PSU and noise section today. PSU seems to be working just fine, but I'm not sure about the noise: When I attach my oscilloscope for testing just a described at the end of the noise section building instructions, I measure a peak to peak voltage of about 18V instead of 10V as shown on the screenshot of Vincent's oscilloscope. The general output looks pretty noise though as if the noise section is working correctly. Is this voltage OK? Or where could I look for a mistake?? I'm confused here ...

Iggy,

On the screenshot of the scoped noise the vertical division is 5V / div so 18V peak voltage is just fine
