Check before you build · 7 values the reader of this schematic was not sure of
- R4296: drawn '110M', read as 10M
- C310: drawn '607p', probably 680p
- C308: revision block says changed to .02uF but the drawing shows .1
- D302/D303: no part number; possibly MR501
- R4293/R4294: drawn R293/R294 on the voice sheet
- C4197: label blurred, could be C4177
- R305B: printed R305 a second time (4.7K, clock gate); may be the deleted R306
