Turn the receiver volume control to maximum. Output Meter .Alignment.-If this method is used, connect t

13、he meter acne the. voice coil, and turn the receiver volume control to maximum. Test-Oscillator.-For all alignment operations, connect the low side of the test -oscillator to the receiver chassis, and keep the output as low as possible to avoid a -v -c action. Calibration Marks. - The tuning dial is

14、 fastened in the cabinet and can not be used for reference during alignment. Therefore calibration marks corresponding to dial readings of 600 kc and 1,500 kc have been stamped in the plate on the front of the chassis, as shown in the accompanying draw- ing. These marks are used for reference during

15、 alignment. Drum and Dial Indicator Adjustment.-As the first step in r -f alignment, check the position of the drum on the front shaft of the gang condenser. With the gang at maximum (full mesh) the drum set -screw should be pointing directly down as shown in the drawing. With the drum in this posi-

16、 tion, and the gang at maximum, move the dial indicator along the drive cord to coincide with the left-hand line as shown. The indicator is held to the drive cord by means of spring clips. After completion of alignment, and after the chassis has been fastened in the cabinet, turn the gang to maximum

17、 and note whether the dial indicator is at the left-hand end mark on the dial; if it is not, loosen the drum set -screw (which is accessible through a slot in the bottom of the cabinet), turn the drum slightly so that the indicator is at this mark, and then tighten the set -screw. After completion o

18、f alignment, seal the i -f core -adjustment screws with household cement. For additional details, refer to booklet, RCA Victor Re- ceiver Alignment.

20、 Tuning. * The oscillator section of the gang condenser has two trimmers, one on top, accessible through a hole in the chassis, and the other on bottom. It may be necessary to adjust both of these trimmers to secure a peak on 1,500 kc. Low -Frequency Alignment: Where additional sensitivity is desire

21、d on these single band receivers, it can be obtained by alignment of the tuning condenser at 600 KC and re -alignment of the trimmer at 1,500 KC as follows: (a) Check alignment of antenna coil with Tuning Wand at 600 KC. If brass end gives increase in signal, bend rotor plates of antenna section of

22、tuning condenser outward to produce maximum peak out- put. If magnetite end gives increase in signal, bend plates of oscillator section of tuning condenser to obtain maximum out- put. (h) Re -align 1,500 KC antenna and osciUator trimmers in the usual manner. PLATE 31419 -DIAL INDICATOR 31420 SP21NG

24、ion of the calibration marks shown in this drawing Adjustments for Electric Tuning These models have six push buttons. The rieht -hand button connects the gang condenser for dial tuning. The other five buttons are for electric tuning of five different sta- tions in the standard -broadcast range. The

25、 station buttons connect to separate magnetite -core oscillator coils and sepa- rate antenna trimmers which must be adjusted for the de- sired stations. Use an insulated screwdriver or alignment tool such as RCA Stock No. 31031. Allow at least five minutes warm-up period before making adjustments. U

26、se a regular antenna for the preliminary adjustments. The procedure is as follows: 1. Make a list of the five desired stations, arranged in order from low to high frequencies. 2. Push in the dial -tuning (right-hand) button, and man- ually tune in the first station on the list. 3. Push in station -b

27、utton No. 1 (left-hand) and adjust No. 1 oscillator core (L12) to receive this station. Screw the core all the way in, to lowest frequency, and then unscrew slowly until the station is received. 4. Adjust No. 1 antenna trimmer (C20) for maximum output on this station. 5. Adjust for each of the remai

28、ning four stations in the same manner. (Clockwise adjustment of oscillator cores and antenna trim- mers tunes the circuits to lower frequencies.) 6. Make a final careful adjustment of the oscillator cores and antenna trimmers, using one or,two feet of wire as an antenna to ensure sharp peaking. Prec

29、autionary Lead Dress.- Dress green lead from antenna coil to switch away from the chassis and gang. 2. Dress green leads from oscillator coils away from the adjustment screws. 3. Dress leads in power -transformer primary circuit to left end of chassis. 4. In 95T5, C27 must be dressed close to chassi

30、s and clear of rotor. 5. In 96E, 96T, and 96T1, dress ground bus from heater of 6H6 close to chassis, and dress blue lead from 2nd I -F transformer to. volume control close to. chassis. 收音机爱 好者资料库 RadioFans.CN PAGE 599-C 95T5, 96E, 96T, 95T1 550-960 650-1080 850-1300 BC.
