Check before you build · 3 values the reader of this layout was not sure of
- D1 next to IC3 (bottom right): the board labels it D1 but the legend only gives 'D3: 12v Zener'; entered as the 12V Zener
- 240pF ceramic between Q1 and Q2 (column 10): printed clearly, unusual value
- Legend 'Q1-Q2: 2N3906, 2N507 etc.': 2N507 is probably a typo for 2N5087; first suggestion entered
