43、ferable to select strong local high -quality stations within a radius of 100 miles. 2. Insert an RCA -6U5 or 6G5 Magic Eye tube in the six -prong socket on the chassis. Use an insulated screwdriver or alignment tool (such as RCA Stock No. 31031) for all adjustments. LEAVE THE FIDELITY SWITCH IN POSI

(This provides capacity coupling between the antenna and the 6A8 grid.) 4. Push in button No. 1 and turn oscillator core

45、No. 1 to bring in the first station on the list. Adjust the core carefully for peak output as indicated by the Magic Eye. Adjust link trimmer No. 1 for ntax. output. . 5.

46、ink trimmer No. 1 for peak output as indicated by the Magic Eye. (Clockwise rotation of cores and trimmers tunes the circuits to lower frequencies, and counter -clockwise adjustment tunes the cir- cuits to higher frequencies.) 6. Push in button No. 2.
