Determine the correct settings of the test -oscillator for these five frequencies. This is accomplished as follows: Tune

9、 in each of the five stations on any standard receiver; zero -beat the test -oscillator against each station, and note the exact setting of the oscillator in each case. 3. Reel up the antenna wire. Connect the high side of test -oscillator through an 80-mmfd. fixed capacitor to the end of the antenn

10、a wire. Clip the low side of the oscillator through a 0.1-mfd. capacitor to one of the chassis -Mounting screws on the bottom of the cabinet. Tune the oscillator to the previously -determined point for the lowest - frequency station, and adjust for a strong output. 310 YE/. RT ISOACOLC ITOnHOT MODEL

11、 95X1 OR 95X11 Alignment Procedure Remove chassis from cabinet. Reel up the antenna wire, and con- nect the high side of test -oscillator through an 80 mmfd. capacitor to the antenna terminal on the antenna trans- former. Connect low side of oscillator to receiver chassis through an .01-mfd. capacit

12、or. Turn gang condenser to minimum (full out), push in the manual -tuning (right-hand) button, tune oscillator to 1,560 kc, connect an output meter across the voice coil, and turn volume control to maximum. Keep antenna roll and lead clear of chassis during all adjustments. Adjust the two trimmers (

13、C3 and C6) on side of gang condenser for maximum output, using lowest pos- sible output from test -oscillator. Turn pointer, so that it is horizontal and pointing to low -frequency end when the gang condenser is at maxi- mum. Check pointer adjustment on a station. Adjustment of Tuning Capacitors The

14、 preferable and quickest method of adjusting the tuning capaci- 4. Turn the volume control of the push-button receiver full clock - tors for five different stations, is to employ a test -oscillator, as de- wise, and push in the left-hand end button. Using an insulated screw - driver, peak capacitors

15、 C20 and C26, at the same time reducing the output of the oscillator in order to secure a sharp peak. (Clockwise adjustment of the capacitors tunes the circuits to lower frequencies, and counter -clockwise adjustment tunes the circuits to higher fre- quencies. The range of each trimmer is three full

16、 counter -clockwise turns from the tight position. Do not unscrew more than three turns.) 5. Push in the second button from left, and adjust C21 and C27 for peak output with the oscillator tuned to the frequency of the second station. 6. Proceed in this manner to adjust each pair of, capacitors for

17、the desired frequencies. 7. Final adjustment may be made in actual reception of the stations. RCA VICTOR DIVISION OF RADIO CORPORATION OF AMERICA, CAMDEN N. J., U. S.
