Blue, green, and black leads to the volume control should be dressed away from the 6K6 -G socket and from leads to this socket. 2. Lea

6、ds to the power transformer should be dressed Adjustments Fo This model has six push buttons. The right-hand button connects the gang condenser for dial tuning. The other five buttons are for electric tuning of five different stations. The station buttons connect to separate magnetite -core coils an

7、d trimmers and to separate antenna trimmers which must be adjusted for the desired stations. Use an insulated screw- driver or alignment tool such as RCA Stock No. 31031. Allow at least five minutes warm-up period before making adjustments. Use a regular antenna for preliminary adjust- ments. The pr

8、ocedure is as follows: 1. Make a list of the desired stations, arranged in the order of the push button ranges shown on the schematic diagram. 2. To adjust buttons Nos. 1 and 2, best results are ob- tained by using a test -oscillator. Using a separate re, ceiver, tune in the desired station for butt

9、on No. 1 and zero -beat the test -oscillator against the carrier of this station. Then, keeping the same setting on the test - oscillator, connect its output to the antenna of the toward the end of the chassis and away from wires to the push button assembly. 3. Power cord lead should be dressed towa

To adjust buttons Nos. 3, 4 and 5, proceed as follows: a. Push in the dial -tuning (right-hand) button, and manually

11、tune in the third station on the list. b. Push in station -button No. 3 and adjust No. 3 oscil- lator core (L14) to receive this station. Screw the core all the way in, to lowest frequency, and then unscrew slowly until the station is received. c. Adjust No. 3 antenna trimmer (C22) for maximum outpu

12、t on this station. d. Adjust for each of the remaining stations in a simi- lar manner. (Clockwise adjustment of oscillator and antenna trimmers tunes the circuits to lower frequencies.) e. Make a final careful adjustment of the oscillator and antenna trimmers, using one or two feet of wire as an ant
