Safety precautions
The Components indentified 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: KΩ(1000Ω), M: MΩ(1000KΩ)
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.
2) Indication on schematic diagram
Voltage indications for REC and PB mode on the sche-
matic diagram are as shown below.
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.

WHEN SERVICING THIS CHASSIS, UNDER NO
CIRCUMSTANCES SHOULD THE ORIGINAL DESIGN
BE MODIFIED OR ALTERED WITHOUT PERMISSION
FROM THE JVC. ALL COMPONENTS SHOULD BE
REPLACED ONLY WITH TYPES IDENTICAL TO THOSE
IN THE ORIGINAL CIRCUIT. SPECIAL COMPONENTS
ARE SHADED ON THE SCHEMATIC FOR EASY
IDENTIFICATION. THIS CIRCUIT DIAGRAM MAY
OCCASIONALLY DIFFER FROM THE ACTUAL CIRCUIT
USED. THIS WAY, IMPLEMENTATION OF THE LATEST
SAFETY AND PERFORMANCE IMPROVEMENT
CHANGES INTO THE SET IS NOT DELAYED UNTIL
THE NEW SERVICE LITERATURE IS PRINTED.
1. Shaded( ) parts are critical for safety. Replace only
with specified part number.
2. Voltages are DC-measured with a digital voltmeter
during Play mode.
