Check before you build · 5 values the reader of this layout was not sure of
- Translucent resistor at column 12, rows C-E, over Q3: text mostly hidden, read as 4.7K
- Electrolytic at column 7, rows A-B: reads '47uF' with the first digit partly hidden; could be 4.7uF
- Electrolytic at column 13, rows E-F: reads '1uF' with the start hidden under its stripe
- Large electrolytic at columns 3-4, rows I-J: reads '220uF' with the first digit partly hidden
- 240Ω resistors (column 3 rows C-F, column 2 rows G-J): printed clearly, unusual value
