TO FACILITATE 3RD VIDEO IF ALIGNMENT: C-118(2.7pf) changedto 2.2pf, Part No.
215115948.

RELIABILITY CHANGE: Circuit modification to reduce pulse an oscillator collector,
0-15. Remove L-501 and R-SIO. Replace with R-53O (1K, 10%, l/ZW) wired between
coil of 0-15 and base of (22-16. See schematic diagram for details.

TO REDUCE THE POSSIBILITY OF VERTICAL JITTER: R-IZZ (82.0) and R- 123 UK)
in video amplifier circuit changed to 820 ohm. 10%, l/ZW. R-403 (82K) in AGC gate
circuit changed to 100K. 10%, l/2w.

TO CENTER AGC DELAY POTENTIOMETER ADJUSTMENT: Remove jumper between
0-11 emitter and 0-12. collector and install diode E-402, Part No. 48065837A02. See
schematic diagram for polarity,

SEE CHASSIS CODING CHANGES C-OO AND C-Ol

TO IMPROVE 0-9 (AIL) AUDIO DRIVER RELIABILITY: Varistor R-3l9 added from
0-9 collector to ground, Part No. 66662632408.

TO IMPROVE HORIZONTAL OSCILLATOR RELIABILITY: Horizontal oscillator tran-
sistor Q-IS (4842) replaced with a more reliable type ASF, Part No. 488134992.

SEE CHASSIS CODING CHANGES C-OO AND C-Ol.

TO IMPROVE 4.5MC SOUND IF (0-6) RELIABILITY: Q-6 (AIL) replaced with AZT,
Part No. 485134970.

TO IMPROVE RELIABILITY OF POWER SUPPLY RECTIFIER DIODES: Diodes E-BOI,
133-802 and E-803 replaced with a more reliable type,

E-BOI, Part NO. 485191A09 (P.I.V, rating ISOOV).
13-802 and E-803, Part No. 485191A06 IP.I.V. rating 750V).
Also see Chassis Coding Change C-Ol".

POWER SUPPLY MODIFICATION TO INCREASE RECTIFIER DIODE PROTECTION:
New parts added and circuit rewired. C-810 (SOmfd/ISDV) Part No. 23665808A08.
R-809 (5,6 ohm, 10%, l/ZW] carbon resistor, R-BOB (22K, 10%, 1W) carbon resistor
added, See schematic diagram for wiring details. A kit, KT-153, which includes com-
ponents and complete wiring instructions to lip-date chassis with coding Ca00 and C-01
is available. Order Part No, 48A65147A63.

TO IMPROVE HEAT DISSIPATION OF VIDEO AMPLIFIER TRANSISTOR 0-4 (4841):
Add fin type heat sink, Part No. Z6510251A02.
