Check before you build · 4 values the reader of this layout was not sure of
- D6 (top left, columns 6, rows B-E): the legend gives no D6 but lists 'D7: 1N5817', and there is no D7 on the board; taken as the same part
- 5.1M at the left edge (rows E-G): printed clearly, unusual value
- 1.5uF film box under the 100nF near Q1: printed clearly, unusual value
- Boost switch: pole count inferred from lug numbers up to 9 in the wiring notes, not stated
