No. Part No. Description Remark Ref. No. Part No. Description Remark 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 and -X mean standardized parts, so they may have some difference from the original one. • RESISTORS All resistors are in ohms. METAL:Metal-film resistor. METAL OXIDE: Metal oxide-film resistor. F:nonflammable • Items marked “*” are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items. • SEMICONDUCTORS In each case, u : µ, for example: uA.. : µA.. uPA.. : µPA.. uPB.. : µPB.. uPC.. : µPC.. uPD.. : µPD.. • CAPACITORS uF : µF • COILS uH : µH The components identified by mark ! or dotted line with mark. ! are critical for safety. Replace only with part number specified. When indicating parts by reference number, please include the board.
