ALIGNMENT INSTRUCTIONS-READ CAREFULLY BEFOREATTEMPTINGALIGNMENT
If receiver Is tobe aligned with picture tube removed, it Is recommended to also remove the 6SN7GT (V15) hori-
zontal oscillator tube to eliminate high voltage shock hazard.
When complete alignment Is tobe performed, It can most conveniently be done In the orderoutlined;

WAVE TRAP ADJUSTMENT
Wave traps A34and ASS are used for specific types of Interference and their alignment will depend upon the type
encountered. With the receiver t uned tothe channel having the Interference set fine tuning control until Interference
Is at maximum. Adjust A34andA35for minimum Interference In the picture and sound. Keeping the cores at approxim-
ately the same relative position. Turn one core 1/2 turn, adjust the other for minimum Interference.
