SCHEMATIC DIAGRAMS / CBA'S AND TEST POINTS

Standard Notes

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 compo-
nents 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 characteris-
tics as specified in the parts list may create shock, fire, or other hazards.

Note:

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.

All resistance values are indicated in ohms (K=10

3

, M=10

6

).

3.

Resistor wattages are 1/4W or 1/6W unless otherwise specified.

4.

All capacitance values are indicated in µF (P=10

-6

µF).

5.

All voltages are DC voltages unless otherwise specified.

Note of Capacitors:

     ML --- Mylar Cap.     PP --- Metallized Film Cap.     SC --- Semiconductor Cap.     L --- Low Leakage type

Temperature Characteristics of Capacitors are noted with the following:

     B --- ±10%     CH --- 0±60ppm/

°

C     CSL --- +350~-1000ppm/

°

C

Tolerance of Capacitors are noted with the following:

     Z --- +80~-20%

Note of Resistors:

     CEM --- Cement Res.     MTL --- Metal Res.     F --- Fuse Res.

Capacitors and transistors are represented by the following symbols.
