acid_bbq, I noticed this question. R14 is changed to 1M to provide a lower voltage to switch the fet on, C9 change to +100uF to provide better dc filtering when using a power supply.
Dear Harald,
I’ve noticed that the BOM you use for this project is slightly different from the one presented in valve wizard. Could you explain what are the impact of these changes? I can’t figure them out…
Best regards and great website by the way.
