Check before you build · 4 values the reader of this schematic was not sure of
- Delay B BBD trim drawn '10K' without taper letter, assumed same as delay A's 10KB
- Master clock 10KB and shift clock 10K: drawn as preset/variable resistors, could be panel pots
- 470uF BBD supply caps: drawn '470µ', could be 47µ on this poor copy
- Right edge is cut off: a third section (1/50 cap, BBD trim 10K, 47K) and the output stage are missing, so the list is incomplete
