Check before you build · 3 values the reader of this layout was not sure of
- 4,75K x2 (columns 10, top left of centre): printed clearly, unusual value
- 13,7K (column 23, upper right): printed clearly, unusual value
- 1uF near the bottom left is drawn as a red box (film) capacitor, not a round can, so not marked electrolytic
