Voltage variations may be noted due to normal production tolerances. • Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. • Circled numbers refer to waveforms. • Signal path. F : MIC C-357 SECTION 4 EXPLODED VIEWS NOTE: • -XX, -X mean standardized parts, so they may have some differences from the original one. • Items marked “*” are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items. • SECTION 5 ELECTRICAL PARTS LIST AMP The mechanical parts with no reference number in the exploded views are not supplied. When indicating parts by reference number, please include the board name. #4 18 17 NOTE: • Due to standardization, replacements in the parts list may be different from the parts specified in the diagrams or the components used on the set. • -XX, -X mean standardized parts, so they may have some difference from the original one. • Items marked “*” are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items. Ref.
