Well, so it shows that the converter has a hard time providing teh rail voltages.+ I fitted DC-DC converter and plugged DC jack of 9V 300mA adapter.
Now the board can deliver guitar sound to next stage.
It make some noise like boiling kettle. (like file below)
But it doesn't work right.
the adapter supply 8.93DC
but DC-DC converter make
+5.946 VDC 225mVAC
-5.963 VDC 237mVAC
demo file (file from my blog)
You need to find out if it's one of the positions that creates the problem or if the problem happens when the number of IC's exceeds a certain value.
You need to start with no IC's in place then populate them one after each other until the rails fall down.
