Check before you build · 4 values the reader of this schematic was not sure of
- Peak-detector cap value not drawn
- NPN/PNP split of the 2SC1815/2SA1015 transistors read from emitter arrows, which are hard to see on the filter followers
- Some 10K/100K counts may be off by one in the dense mix section
- Input-stage 200K values written small, could be 100K
