Check before you build · 7 values the reader of this layout was not sure of
- 3.3nF film cap drawn transparent over a cut near Q4 / the Color wires: digits partly covered, read as 3,3nF
- 33K transparent resistor over a cut below Q3 (centre right of board): read as 33K, could be 39K
- 100Ω transparent resistor crossing Q3: read as 100Ω through the transistor body
- 100uF electrolytic between D3/D4 and the CLR resistor: unit clipped by the can edge, could read 100nF but drawn as an electrolytic
- 20nF film cap next to Q1: printed clearly, unusual value
- 10pF yellow cap next to Q1: small text, could be 100pF
- Hot pot: legend prints 25kW (W taper)
