Re: CLK2 low level
Just interchange the raduinos between two main boards and see how it does.toggle quoted messageShow quoted text
If one raduino works well and other is silent then it is the raduino at fault.
Else check the first mixer transformers, gently rocking them migh show up a short.
I have had one that was shorted.
