VIDEO IF ALIGNMENT
If the scope to be used does not have a sensitivity of 1 m illivolt per inch a suitable pream plifier may be necessary. A VHF signal generator of cry stal
accuracy should be used to provide m arkers.
Beginning with step 7 the sweep or signal generators will be connected to the front term inal of the K E crystal m ixer. Since extrem ely short leads
must be employed in making these connections it is recommended that the KRK12C input head shown in Fig. 4 should be constructed and used in o rder to
obtain reliable response curves.
Three 7. 5 volt batteries capable of withstanding considerable current drain are required.
Connect two 7. 5 volt batteries in series with a 1000 potentiom eter across the 15 volt combination. Also, connect a 1000ft potentiometer across the third
7. 5 volt battery. Connect the positive side of the 7. 5 volt battery to chassis and the potentiometer arm to the ungrounded side of C55 and adjust for-6 volts
Connect the synchronized sweep voltage from the sweep generator to the horizontal input of the oscilloscope for horizontal deflection.

KRK12C VHF TUNER ALIGNMENT
In step 20 choose the proper pad ( see Fig. 11) to match the output impedance of the sweep generator to be used. If the sweep generator does not have
built in markers couple a VHF signal generator loosely to antenna term inals to provide markers.
Connect the negative lead of the 7. 5 volt bias supply to the tuner AGC terminal. Connect the positive side to chassis. Adjust the potentiometer arm for
- 2 volts at tuner AGC terminal.
To minimize RF-IF interaction remove the RF oscillator tube (V2/6AF4) from its socket.
Tuner alignment as outlined below requires the use of a heterodyne frequency meter.
Connect the synchronized sweep voltage from the sweep generator to the horizontal input of the oscilloscope for horizontal deflection.
The sweep generator output lead should be terminated with its characteristic impedance, usually 50 ohms.

MISCELLANEOUS ADJUSTMENTS
HORIZONTAL SWEEP CIRCUIT ADJUSTMENTS
HORIZONTAL OSCILLATOR ALIGNMENT - Turn the set on and tune in a TV station, preferably a test pattern. If necessary, synchronize
the picture with the horizontal hold control (R10B).
(1) P rese t the horizontal drive control (R21A) until the white foldover just disappears from the raster.
(2) Adjust the horizontal locking range trim m er . (Bl) one fourth turn from maximum clockwise position. Adjust the width coil slug
(B2) until the adjusting screw is approximately 2/ of the way out.
( ) Set the horizontal hold control to the center of its range.
(4) If necessary, adjust the horizontal frequency slug (B ) until the picture synchronizes horizontally.
(5) Connect the vertical amplifier of the oscilloscope to terminal "C" of L 8. A djust the horizontal waveform slug (B4) fo r response
sim ilar to Fig. 20. While adjusting B4 keep the picture in sync by readjusting the horizontal hold control. Remove the oscilloscope.
(6) Set the horizontal hold control to its maximum counter clockwise position.
Momentairly remove signal by switching off channel and back again. If picture rem ains in sync adjust B slightly and again switch
off channel and back. If necessary, repeat this process until picture falls out of sync with diagonal bars sloping down to the left.
Turn the horizontal hold control clockwise noting the least number of diagonal bars obtained ju st before the picture falls into sync.
Adjust Bl slightly clockwise if more than three diagonal b ars were present before picture pulled into sync. If less than two bars
were present adjust Bl slightly counter clockwise.
(7) Turn the horizontal hold control fully counter clockwise and switch off channel and back again and recheck the number of bars
present at the pull-in point (70 degrees clockwise rotation). Repeat the above procedure until 2 o r bars are present at the
pull-in point
HIGH VOLTAGE ADJUSTMENT
Turn the contrast control and brightness control to their maximum counter clockwise positions.
Connect the probe end of high voltage probe through a short length of high voltage anode lead to the corona cup on the base of the A (V24).
Set the meter for a 20KV reading. Set the high voltage control (R25A on rea r of H. V. cage) for 19. 5KV on VTVM.
Turn contrast and brightness controls clockwise until picture appears on picture tube.
Adjust the focus control for best focus. Adjust convergence control for best convergence in the center portion of the picture tube.
Adjust the width coil slug (B2) for i inch horizontal over scan of the viewing area. Turn the horizontal drive control clockwise as far as
possible without the presence of white foldover lines in the raster. Recheck the operation of horizontal hold control for proper pull in
action as outlined under "Horizontal oscillator alignm ent” ( Steps 6 and 7)
HIGH VOLTAGE PERFORMANCE CHECK
Connect a 0-1MA DC milliam m eter in the cathode circuit (Pins 1 & 8) of the 6BD4 (V25). A reading of . 6 MA should be obtained when
the high voltage is 19. 5KV. Remove m illiam meter and high voltage probe.
Adjust the vertical height and vertical linearity controls so that after final adjustm ent a vertical overscan of 1/4 inch at top and bottom of
viewing area is obtained.
COLOR AFC ALIGNMENT

Adjust A40 for zero beat (indicated by slow swing of
VTVM pointer. Zero beat may also be observed on
scope or picture tube screen). Remove short from
point <^> .
8. DCjprobe to point
<M> . Common
to cnassis.
Shunt .58MC crystal (M14) with 15MMF capacitor.
Adjust AFC balance control (R20A)for zero reading
on VTVM. Remove 15MMF capacitor across M14.
HORIZONTAL DYNAMIC CONVERGENCE CIRCUIT ALIGNMENT
Clip the scope probe on the insulated lead to pin 1 ( convergence anode) of the picture tube socket.
Turn the vertical convergence amplitude control to its maximum counter clockwise position. Set the vertical convergence shape control
to its midrange position. Turn the horizontal convergence amplitude control to its maximum clockwise position.
Adjust the horizontal convergence phase control slug, A41, for maximum sine wave amplitude sim ilar to Fig. 22. Turn the horizontal
convergence amplitude control to its maximum counter clockw ise position. aAdjust the horizontal dynamic convergence slug, A42, for
co rre ct phasing of minimum waveform with horizontal pulse on top of sine wave as in Fig. 2 .
Turn horizontal convergence amplitude control fully clockwise and adjust A41 for waveform sim ilar to Fig. 2 . Return horizontal convergence
amplitude control to its maximum counter clockwise position.
