Check before you build · 3 values the reader of this layout was not sure of
- 4.7nF at column O rows I-J, left of D6: drawn as a round electrolytic can (same pink style as the 47uF) but printed 4,7nF; may be meant as 4.7uF
- 82Ω at column G rows G-H: printed clearly, unusual value
- Q1-Q3, Q5, Q6: legend lists 2N5172, 2N5225 or BC318C as the original parts and BC550C, 2N5088, MPSA18 as substitutes; entered the first
