REMARKS
Check for response similar to Fig. 5.If
response isnot flat between limits shown,
detune A22 counterclockwiseuntil single
peak appears. Adjust A21 until peak falls on
213MC marker. Adjust A22for response
similar to Fig. 5.
Check for response Indicated by dotted lines
In Fig. 6Aand6B.If necessary, adjust for ,
mirror image of original response curve.
(Tilt In opposite direction.) If response curve
appears as in Fig. 6A, adjust A23andA24
untilcurve appears asin Fig. 6B. This adjusi
ment over compensates to allow for channel
13 adjustment.Repeat steps 17and18 until
centered and symmetrical response curves
are obtained on channels 7 and13.
Adjust for symmetrical response approxi-
mately center of bandpass. Adjust A26
counter clockwise until single peak appears.
Adjust A25 untilpeak falls on 85MC marker.
Adjust A27for maximum curveamplitude
and symmetry of single peak. Retouch
SLIGHTLY , if necessary, A25andA26for
symmetrical response centered at approxi-
mately the 85MC markerpoint similar to
Fig. 5.
Check response curve for symmetrical
responsecentered at approximately 44MC.
If necessary, retouch SLIGHTLY A25,A26
and A27for symmetrical responsecentered
at approximately the 44MC marker point
Repeatstep 19tobe sure channel 6 (85MC)
Is withinproper limits on response curve
similar to Flic. 5.
VIDEO PEAKINU COIL ADJUSTMENT
In cases of excessiveovershooting or smear on some stations, It maybe necessary to adjustA28.Alignment ofthe tuner and IF portions ofthe
receiver must be correct before this adjustment Is made. Proper adjustment ofA28 Is the point of minimum smear and trailing whites.After
adjusting A28onone channel,checkotherchannels to make certain picture quality hasnot beenaffected.
