File name 86662sch.pdf SECTION 4 CHARTS AND DIAGRAMS NOTES OF SCHEMATIC DIAGRAM Safety precautions The Components identified by the symbol are critical for safety. For continued safety, replace safety critical components only with manufacturer's recommended parts. 1. Units of components on the schematic diagram Unless otherwise specified. 1) All resistance values are in ohm. 1/6 W, 1/8 W (refer to parts list). Chip resistors are 1/16 W. K: KØ (1000Ø), M: MØ (1000KØ) 2) All capacitance values are in µF, (P: PF). 3) All inductance values are in µH, (m: mH). 4) All diodes are 1SS133, MA165 or 1N4148M (refer to parts list). 1 REC mode 2.5 (5.0) PB mode 1.8 PB and REC modes (Voltage of PB and REC modes are the same) 2 3 4. Voltage measurement 1) Regulator (DC/DC CONV) circuits REC : Colour bar signal. PB : Alignment tape (Colour bar). -- : Unmeasurable or unnecessary to measure. 4) Indication on schematic diagram Voltage Indications for REC and PB mode on the schematic diagram are as shown below. Note: If the voltages are not indicated on the schematic diagram, refer to the voltage charts. 5. Signal path Symbols The arrows indicate the signal path as follows. NOTE : The arrow is DVC unique object. Playback signal path 2. Indications of control voltage AUX : Active at high. AUX or AUX(L) : Active at low. 3. Interpreting Connector indications 1 2 3 1 2 3 Playback and recording signal path Recording signal path (including E-E signal path) Removable connector Capstan servo path Drum servo path Wire soldered directly on board (Example) R-Y Playback R-Y signal path Recording Y signal path 1 2 3 1 2 3 4 Non-removable Board connector Y 6. Indication of the parts for adjustments Board to Board The parts for the adjustments are surrounded with the circle as shown below. Connected pattern on board The arrows indicate signal path 7. Indication of the parts not mounted on the circuit board "OPEN" is indicated by the parts not mounted on the circuit board. R216 OPEN S40889-01 4-1 CIRCUIT BOARD NOTES 1. Foil and Component sides 1) Foil side (B side) : Parts on the foil side seen from foil face (pattern face) are indicated. 2) Component side (A side) : Parts on the component side seen from component face (parts face) indicated. 2. Parts location guides Parts location are indicated by guide scale on the circuit board.
