- R362: designator not legible at this resolution
- R363/R368/R369, R373/R378/R379: digits blurred, read by the voice 1/voice 2 numbering pattern
- Capacitors: designators (C3100-C3132, C36x) mostly illegible in the low-resolution scan, given as quantities
- U323: could be U333's neighbour U325; the label is blurred
- D306: could be D302
