Standard Notes
WARNING
Many electrical and mechanical parts in this chassis
have special characteristics. These characteristics
often pass unnoticed and the protection afforded by
them cannot necessarily be obtained by using
replacement components rated for higher voltage,
wattage, etc. Replacement parts that have these
special safety characteristics are identified in this
manual and its supplements; electrical components
having such features are identified by the mark “
#
” in
the schematic diagram and the parts list. Before
replacing any of these components, read the parts list
in this manual carefully. The use of substitute
replacement parts that do not have the same safety
characteristics as specified in the parts list may create
shock, fire, or other hazards.
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 STOP modes on
the schematics are as shown below.
