REMARKS
Check for response similar to Fig. 5 ,
Use 210MC and 216MC markers to establish
channel limits. If response is not flat be-
tween limitsshown, detune A26 counter
clockwise until single peak appears. Adjust
A27 until peak falls on 213MC marker .
Adjust A26for response similar to Fig. 5.
Check for response as indicated by
dotted lines in Fig. 6Aand6B.Use
174MC and 180MC markers to establish
channel limits. If necessary, adjust for
mirror image of originalresponse curve
(tilt in opposite direction) . If response
curve appears as in Fig. 6A adjust A28and
A29 until curve appears asin Fig. 6B. This
adjustment over compensates to allow for
channel 13 adjustment. Repeat steps 20and
21 untilcentered and symmetrical response
curves are obtained on channel 7 and13.
Adjust for symmetrical response approxi-
mately center bandpass. Adjust A31 counter
clockwise untilsinglepeak appears. Ad-
just A30 until peak falls on 85MC marker .
Adjust A32for curve of maximum amplitude
and symmetry of singlepeak. Retouch
SLIGHTLY A30andA31if necessary, for
symmetrical response centered at approxi-
mately the 85MC marker point (Fig. i) .
Check response curve for symmetrical
responsecentered at approximately 44MC.
If necessary, adjust A33for flat-topped
symmetrical response centered at approxi-
mately the 44MC marker point. Repeat
step 22tobe surechannel 6 (85MC) Is
within properlimits on response curve
(Fig. 5).
VIDEO PEAKING COIL ADJUSTMENTS
In case of excessive overshoot or smear on some stations, it may be necessary to adjust A34. Alignment of the tuner and IF
portions ofthe receiver must be correct before adjusting A34. Counter clockwise adjustment will reduce the amount of over-
shoot and clockwise adjustment willreduce the amount of smear. Proper adjustment point is the point of minimum smear and
trailingwhites. After A34is adjusted, check all otherstations to make certain they have not been seriously affected.
