WARNING
Critical components having special safety characteris-
tics 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 fol-
lowing symbols.
Notes:
1. Do not use the part number shown on these draw-
ings 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. Prefix symbol "CN" means "connector" (can dis-
connect and reconnect).
Prefix symbol "CL" means "wire-solder holes of the
PCB" (wire is soldered directly).
4. How to read converged lines.
Examples:
(1). "1-D3" means that line number "1" goes to area
"D3."
(2). "1-B1" means that line number "1" goes to area
"B1."
5. All resistance values are indicated in ohms
(K=10
3
, M=10
6
).
6. Resistor wattages are 1/4W or 1/6W unless other-
wise specified.
7. All capacitance values are indicated in
µ
F
(P=10
-6 µ
F).
8. All voltages are DC voltages unless otherwise
specified.
9. Voltage indications PLAY and REC modes on the
schematics are as shown below.
