- Diode at column 20, rows H-J (white body) is printed 'D2' although a D2 already sits beside D1 at the left; taken as the legend's D3
- IC1-IC2: legend gives no part number beyond 'Metal can dual op amps or sanded 4558s'; entered as 4558
- D3: legend gives only 'NOS magic germanium diode or a boring Shottky diode', no part number
