WARNING
Critical components having special safety
characteristics are identified with a
#
by the Ref. No.
in the parts list and enclosed within a broken line*
(where several critical components are grouped in one
area) along with the safety symbol
#
on the
schematics or exploded views.
Use of substitute replacement parts which do not have
the same specified safety characteristics may create
shock, fire or other hazards.
Under no circumstances should the original design be
modified or altered without written permission from
Philips Consumer Electronics Company. Philips
assumes no liability, express or implied, arising out of
any unauthorized modification of design. Servicer
assumes all liability.

Capacitor Temperature Markings
Capacitors and transistors are represented by the
following symbols.
Notes:
1. Do not use the part number shown on these
drawings for ordering. The correct part number is
shown in the parts list, and may be slightly
different or amended since these drawings were
prepared.
2. To maintain original function and reliability of
repaired units, use only original replacement parts
which are listed with their part numbers in the
parts list section of the service manual.
3. How to read converged lines.
Examples:
(1). "1-D3" means that line number "1" goes to the
line number "1" of the area "D3".
(2). "1-B1" means that line number "1" goes to the
line number"1" of the area "B1".
4. All resistance values are indicated in ohms
(K = 10
3
, M = 10
6
).
5. Resistor wattages are 1/6W unless otherwise
specified.
6. All capacitance values are indicated in
µ
F
(P = 10
-6 µ
F).
7. All voltages are DC voltages unless otherwise
specified.
8. Voltage indications for PLAY and REC modes on
the schematics are as shown below.
