- Transistor types: six transistors but the labels are 'Q1' and '2n 2907' above the board and '2n 2907, 2n 2222, 2n 2907, MPSA18' below; Q1 is entered as 2N3391 from the legend, and the '2n 2907' above is taken to be the transistor under Q1, giving three 2N2907
- 20n at top left, 30n (two) and 50n: printed clearly, unusual values
