Hi, maybe someone can help me figure out what i've done wrong with this.
I've finished my units and everything works except the HPF.
I have soldered 100nf as well and wired the spdt switch so that lug 1 and 2 connect to the holes on the PCB.

I checked with the schematic but as that part of the design isn't drawn up, i'm not quite sure if i have it connected properly.

If someone can help me out would be great !

I had to remove the jumper below DOA 1 to get HPF to work.
