ALIGNMENT INSTRUCTIONS
ALIGNMENT INSTRUCTIONS-READ CAREFULLY BEFORE ATTEMPTINGALIGNMENT
Allow 15 minutes for receiver and test equipment to warm up. There should bea goodbondbetween chassis and test equipment.
Connect the deflectionyoke and speaker during alignment.
Do not remove the horizontal oscillator tube(V15) to disable the high voltage. The high voltage leadshould be securelytaped and keptawayfrom the
chassis. The IF shieldmust bein place.

REMARKS
Check for response similar to Fig. 5. If
response isnot flat between limits shown,
detune A22 counter clockwise until single
peak appears. Adjust A21 untilpeakfalls
on 213MC marker. Adjust A22for response
similar to Fig. 5.
Check for response indicated by dotted lines
In Fig. 6 A and6B. If necessary, adjust
mirror Image of original response curve,
(tilt in opposite direction). If response curve
appears as In Fig. 6A, adjust A23andA24
until curve appears as In Fig, 6B. This
adjustment over compensates to allow for
channel 13 adjustment Repeat step's 17and
18 until centered and symmetrical response
curves are obtained on channels 7 and13.
Adjust for symmetrical response approxi-
matelycenter of bandpass. Adjust A26
counterclockwiseuntil signal peak appears.
Adjust A25 untilpeakfalls on 85MC marker-
Adjust A27for maximumcurveamplitude and
symmetry of single peak. Retouch SLIGHTLY,
If necessary, A25andA26for symmetrical
response centered at approximately the
85MC marker point similar to Fig. 5.
Check response curve for symmetrical
response centered at approximately, 44MC.
If necessary, retouch SLIGHTLY A25, A26
at approximately the 44MC marker point
Repeat step 19 to be sure channel 6(8 SMC)
i s within proper limits on response curve
similar to Fig. 5. Remove 68n resistor
and reconnect IF coupling link. Remove
bias supply and reconnect AGC lead to tuner
terminal.
VIDEO PEAKING COIL ADJUSTMENT
In cases of excessiveovershooting or smear on some stations, itmaybe necessary to adjust A2B. Alignment ofthe tuner andIF portions or the
receiver must be correct before this adjustment is made. Proper adjustment ofA28isthe point of minimum smear and trailingwhites.
After adjusting A28onone channel,check others to make certain picturequality hasnot beenaffected.
