Check before you build · 3 values the reader of this layout was not sure of
- 3.3K at column 18, rows K-M (semi-transparent resistor beside the lower 47uF): the first digit is hidden behind the capacitor, only ',3K' shows; 3.3K is the best reading
- 130K at column 5, rows C-F: printed clearly, unusual value
- 120nF at column 5, rows I-K: printed clearly, unusual value
