Check before you build · 3 values the reader of this layout was not sure of
  • 131K at column 7 rows M-P: printed clearly, unusual value
  • 1uF at A8 (top, over a cut) is drawn as a translucent circle, taken as an electrolytic; the other three 1uF are film boxes
  • Drive is drawn as a 1M trimmer on the board while the legend also names a Gain 100kA pot; both listed
