DO NOT ATTEMPT TO ALIGN THE RF SECTION UNLESS IT IS DEFINITELY KNOWN TO BE NECESSARY. Usually alignment will not be n

9、ecessary unless a coil has been damaged or replaced. Since separate coils are used for each switch position It should be necessary to re-align only the deflective channel. Adjustment of A12 and A13 may be necessary when tubes are replaced in the RF Tuner. Adjustments are made by changing the Inducta

10、nce of the Individual colls. Coupling Is fixed except for channels #2 and 13. Coupling on channel tZ may be varied by sliding the copper rings on the coil form. Coupling on channel #3 may be adjusted if necessary by moving turns at the insides of the coils. Frequency adjustment is made in each case

11、by expanding or com- pressing the coils. The upper three switch positions each cover two channels and must be sufficiently broad. The fine tuning control should be at center position during oscillator alignment. DUMMY ANTENNA Resis- tive (See above ) ii SIGNAL GENERATOR COUPLING Antenna termi- nals

42、agnets mounted on tne rocus and de- flection assembly. The assembly may be turned the necessary direction, and the amount of correction may be changed by rotating the large magnet with respect to the smaller one and by sliding the two magnets together or apart. Maximum effect is with the two magnets

43、 close together and aligned. Mini- mum effect Is achieved by turning the large magnet to oppose the small one.
