The parts list prints C318 in the 1 µF line and again as a 0.047 µF polycarbonate part. The cassette control circuit diagram (p. 36) shows C316 as the 1 µF electrolytic, C318 as 0.047 µF, and C314 as a non-polarised 1 µF part; see the [[Amstrad CPC 6128 Capacitor Replacement Guide]].<ref name="sm6128cct">Amstrad Consumer Electronics plc, ''CPC6128 Micro Computer / CTM644 Colour Monitor / GT65 Green Monitor Service Manual'', p. 21 "Electrical Parts List" and p. 36 "Cassette Control Circuit Diagram".
