PRODUCT SAFETY NOTICE:
Product safety should be considered when a
component replacement is made in any area
of a receiver.
Components indicated by a mark
circuit diagram show components whose
values have special significance to product
safety. It is particularly recommended that only
parts specified on the part service manual be
5 5 - - A A
5 5 - - A A
used for components replacement pointed out
by the mark.

CIRCUIT DIAGRAM NOTICE:
1. All resistance value are in ohms, K=1,000, M=1,000,000.
2. All resistance rated wattages are 1/6W unless otherwise noted.
3. Excepting electrolytic capacitors, all capacitance values of less than 1
are expressed in µ F and more than 1 are pF.
4. All capacitance rated voltages are 50V unless otherwise noted.
in this
5. All inductance values are in µ H.
6. Voltage readings take with a "VTVM" are from point indicated chassis
ground. Voltage readings taken by using PAL colour bar signal are
with all controls at normal position. Some voltage may vary with signal
strength.
7. Waveform were taken with PAL colour bar and controls adjusted for
normal picture. Waveforms were taken by using a wide band oscillo-
scope and a low capacity probe.
8. This circuit diagram covers a basic or representative chassis only. There
may be some components or partial circuit differences between the
actual chassis and the circuit diagram.
9. Parts specified with "X" are not installed in this model.
10. Parts specified with "J" are just jumper wires.
