As I was saying, the led wiring seems strange. I’ll double check but I already spent many time on this part of the circuit and got those results.
What seems wrong with the clipping switch for you ?
This part looks like the same found for the Pauper to me.
Many changes from the original KOT actually.
- No Distorsion clipping diodes. Vref to OD Diodes
- The high gain mod is 100k from gain 2 to gain 3 and 100k coming from Gain 1 (instead of 10K).
- Turbo mode (even higher gain) only on the POT is 5k after gain instead of 10k. Actually it's 2 10k...
