KRK12C VHF TUNER ALIGNMENTIn 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 m arkers couple a VHF signal generator loosely to antenna term inals to provide m arkers.Connect the negative lead of the 7. 5 volt bias supply to the tuner AGC term inal. Connect the positive side to chassis. Adjust the potentiometer a rm for - 2 volts at tuner AGC term inal.To minimize R F-IF interaction remove the RF oscilla tor tube (V2/6AF4) from its socket.Tuner alignment as outlined below requires the use of a heterodyne frequency m eter.Connect the synchronized sweep voltage from the sweep generator to the horizontal input of the oscilloscope fo r horizontal deflection.The sweep generator output lead should be term inated with its charac te ristic impedance, usually 50 ohms.

Slide the yoke in a fo rw ard d irec tio n until an a ll red r a s te r is obtained. Check to see that the grounding sp rin g s on the yoke b rack e t a re contacting the p ictu re tube shield. Replace the fie ld neu tra liz ing coil (T9) plug in its socket. Adjust the field n eu traliz ing contro l (R18) fo r b est r a s te r edge purity . If ad justm ent of deflection yoke affected the purity , sligh tly rea d ju s t T8 and R17A.
