Hi all, I can't seem to find an explanation for this anywhere, but Gyraf's schematic has 3 10k resister but the PCB layout only has 2. It seems the one linking the positive and ground after the filter layout is missing. Or am I missing something?
As the signal is leaving the filter section. The signal leaves from in between the 10k and 1k resister. Then before it goes to the make up gain and prior to going to the 220n cap there is another 10 k resister that goes from the main signal to the ground. This is not on the pcb layout. Here is the schematic.

And here is the layout
