DESCRIPTION OF SCHEMATIC DIAGRAM
NOTE:
7. The unit of resistance .. ohm .. is omitted (K: 1000 ohms,
M: 1 Meg ohm) .
2. All resistors are 1/8 watt , unless otherwise noted.
3. All capacitors are pF, unless otherwise noted P:ppF.
4. (G) indicates 1:2% tolerance may be used.
5. .:;. indicates line isolated ground .
6.
-Qo indicates hot ground .
VOLTA GE ME A SUREMENT CONDITION S:
1. All DC voltages are measured with AC voltmeter
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 1000p.V 8 & W or Color
signal,

WAVEFORMS
WAV EF ORM MEASUREME NT CONDITIONS:
1. Photographs taken on a standard gated rainbow 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.
2.
(> i nd icates waveform check po ints ( See chart ,
waveforms are measured from
