Check before you build · 6 values the reader of this schematic was not sure of
- Q1, Q2: legend designators applied to the two unlabeled flip-flop transistors by inference
- Q5: in the legend (2SC3378) but not found on the drawing
- Q9, Q10: not in the legend
- Q8: legend says 2SK118 but it is drawn as a bipolar emitter follower
- ×1 150n: label sits beside the 3k3 resistor; read as the polarized tantalum cap at the Low pot
- ×1 ?: Q12 emitter resistor has no value
