Check before you build · 5 values the reader of this schematic was not sure of

R18, R24, R40, R41, R44, R47, R50, R53: handwriting shows no clear decimal point (could be 47K) but all-pass pairs should match the clear 4.7K partners
R117: value cut off at the bottom edge, 220 1/2W assumed by analogy with R101
CR10: designator partly cut off
R129, R130, R131: pots vs trimmers not stated
Q1, Q2 'C1852' as written
