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 recom-
mended 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).
2. Indications of control voltage
AUX : Active at high.
AUX or AUX(L) : Active at low.
3. Interpreting Connector indications
Note: If the voltages are not indicated on the schematic
diagram, refer to the voltage charts.

PB and REC modes
(Voltage of PB and REC modes
are the same)
PB mode
REC mode
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 sche-
matic diagram are as shown below.
5. Signal path Symbols
The arrows indicate the signal path as follows.
NOTE : The arrow is DVC unique object.
Playback signal path
Playback and recording signal path
Recording signal path
(including E-E signal path)
Capstan servo path
Drum servo path
(Example)

Playback R-Y signal path
Recording Y signal path
6. Indication of the parts for adjustments
The parts for the adjustments are surrounded with the circle as
shown below.
7. Indication of the parts not mounted on the circuit board
“OPEN” is indicated by the parts not mounted on the circuit
board.
