DESCRIPTION OF SCHEMATIC DIAGRAM

NOTES:

1. The unit of resistance "ohm" is omitted.

(K=k

)

2. All resistors are 1/10 watt, unless otherwise noted.

3. All capacitors are

F, unless otherwise noted.

(P=pF=

µµ

4. (G) indicates

2% tolerance may be used.

5. indicates line isolated ground.

VOLTAGE MEASUREMENT CONDITIONS:

1. All DC voltages are measured with DVM connected

between points indicated and chassis ground, line

voltage set at 120V AC and all controls set for normal

picture unless otherwise indicated.

2. All voltages measured with 1000

V B & W or Color

signal.

WAVEFORM MEASUREMENT CONDITIONS:

1. Photographs taken on a standard gated color bar

signal, the tint setting adjusted for proper color. The

wave shapes at the red, green and blue cathodes of

the picture tube depend on the tint, color level and

picture control.

indicates waveform check points (See chart,

waveforms are measured from point indicated to

chassis ground.)
