6、 new Victor Radio and Victor Radio with Electrola. Embodied in these new instruments are all the features which are essential to the listeners complete enjoyment and appreciation-quality musical reproduction, simplicity and economy of operation, and a high degree of sensitivity and selectivity. The

7、reproducing system comprises the radio unit, the power-amplifier, and the electro dynamic reproducer. In the combination Radio with Electrola the electric pickup is used to translate into electrical energy the mechanical vibrations of the needle in the record grooves. Unsurpassed tone quality and co

8、ntrollable volume without distortion for both radio and record reproduction are obtained through the power-amplifier and electro dynamic reproducer. All power for operation is obtained from the electric light line, and is controlled by a small snap switch on the radio panel. The tuning range of the

9、instrument covers the entire broadcast band of 550 to 1500 kilocycles (545 to 200 meters).

13、Radiotrons inlheir io.kt, in the radio set as shown. Insert the additional Radiotrons in the power-amplifier unit as shown at the bottom of Fie. l. 4. Installing Selector Lamp-Remove the co,ier over tlie metal compartment in back o the selector scale. T.his cover has.a sprilg clip and can be removed

14、 readily. place the selec_ tor lamp in its socket, a_nd replace the covcr, taking care that it is fitted properly so that it will not rattle. 5. Connections to Antenna and Ground-Connect the lead-in wire from thc antenna to the antenna bindirrg post on the back of the radio set. Connect the srouni w

15、ire. to the ground binding post. The successful operaiion of the ins.trument is largelv dependent upon a good antenna and ground. See pages 9 and l0 for a dcscription o.-f the best anrenna and ground to be used. 6. Connections to Power Supply-Connect one end of the power supply cord ro the pouer-imp

16、lifier unit attachment plug, (see Fig. l) and the oiher end bf this cord to a lamo soclet or any other convenient electrical outlet of the prop, rating. Neaer connect the power cord to a direct currenr i;rrLil. 2rto o! alternating current circuit of any rating except 105 to 120.volts, 50 to 60 cycle

20、the right. With a small screw driver, turn the UX-226 hum control in the power-amplifier unit, shown in Fig. 1, slightly in either direction as required until the hum of the instrument is a minimum. Turn the transfer switch to the left to the radio position and also turn the radio volume control to

21、the left. With a small screw driver, turn the UY- 227 hum control in the radio set (see Fig 1) to the right or left as required until the hum is a minimum. Improved reception and reduction of hum may sometime,s be effetted by reversing the prongs of the power supply cord. This can be done by removin

22、g the power plug, turning it through a half circle, and reinserting it. Excessive hum may sometimes be caused by one gf the Radiotrons not functioning properly, particularly the UY-227. A new Radiotron should be tried i this condition is noted. 8. Rearranging Radiotrons-Improved reception can someti

23、mes be effected by rearranging the Radiotrons UX-226 iri their various sockets in the radio set and listening to the reproduction until the best combination is found. 9. Harmonic Modulator-The harmonic modulator, which controls emphasis on the bass section of the scale, can be regulated to suit indi

24、vidual preference or the acoustic qualities of an unusual room. This control, shown in Fig. I is set in the factory for the best reproduction over the entire musical range, and should not ordinarily require further 6 l J I N RadioFans.CN 收音机爱 好者资料库 RadioFans.CN 收音机爱 好者资料库 adjustment.

MountingTurntable-In the combination Radiowith Electrola move the electric pickup arm to the right as far as possible. Holding the turntable in both hands, carefully lower it over

26、 the turntable spindle. Make certain that the slot in the turntable is engaged u-ith the pin in the spindle. 11. Regulating Speed-Regulate the speed of the turn- table to 78 revolutions per minute rvith the electric pickup and needle on the record. This can be done bv placing i piece of paper under

27、the edge of the record on the turntabli, count- ing the number of revolutions for one minute, and turning the speed regulator screw, shown in Fig. 3, rvith.a small screri driver until the proper speed of 78 revolutions per minute is obtained. RADIO OPERATION Referring to Fig. 2 for location of the c

28、ontrols: l. Snap the pouer srvitch to the right to the on position. 2. Turn the transcr snitch to the left to the Radio position. 3. Turn the radio volume control about half way to t he righ t. 4. After approximately 30 seconds from the time the p.owej s.vitch is first turned on (this interval is re

29、quired for the Radiotrons to heat properly), move the station selector lever over the scale, lifting the lever slightly rvhile it is being moved, until a station is heard. 5. If no station is heard, it may be that no local or pover- ful stations are broadcastinq, in vhich case the volume iontrol sho

30、uld be advanced to the iighr to maximum, and the station selector lever again moved over the scale until a station is heard. It will be notcd tl.rat the station selector is readily oDerated as a lever_, and that the fine vernier adjustment is o6tained by turning. the vernier control knob slightly to

31、 the right or left as requrred. 6. Adjust thc vernicr control for maximum volume by turning the knob to the right or let. 7. Regulate to the desired volume by means of the radio volume control. 8. Aftcr bccoming morc familiar rrith the simple and rapid tuning operation, it uill be possible to slide

LOGGING STATIONS The oositions on the sclector scale at which difrerent stations are receivcd can be markcd on the light space pro- vided if desired. The slot on the indic

34、ator is so shaped that the scale can be accurately marked w-ith a soft lead pencil to ensure ease of crasure. It will be noted that the scale is cali- brated directly in kilocycles, so that the lorv requency stations (high uave length) will be rcceived touard the left end and ihJ ttiglr frequency st

35、ations (lorv u.ave. lergth) toward the risht end of the scale. A short line should be placed opposite th1 scale calibration at which the station is received, and the station call lettcrs then marked vertically as shown in Fig. 2. ELECTROLA OPERATION Rcferring to Figs. 2 and 3 for the location of the

36、 controls l. Turn the transfcr switch to the right to the trecord position. 2. Snap the power switch to the right to the on posi- tion. 8 RadioFans.CN 收音机爱 好者资料库 RadioFans.CN 收音机爱 好者资料库 3. Insert a new Victor steel needle or a Victrola Tunss- tone needle in the electric pickup, and tighten the needl

37、e scrEw firmly. . .4. After placing the record on the turntable, swing the pickup arm to the outer edge of the record, and puil the iotor starting switch forward. 5. After the turntable has acquired speed, lower the electric pickup onto the record. 6. Regulate the volume by means of the control. Max

38、imum volume is obtained when turned all the way to the right. record volume the control is 7. To discontinue operation of the Electrola. lift the electric pickup and movi it to the right to clear tire record. The motor will be stopped automaticaly at the end of a Victor eccentric groove record. (All

39、 Orthophonic records have this eccentric groove.) When playing records without the eccentric groove-, stop the motor by pushing the motor starting switch toward the rear of the cabinet. Snap the power switch on the radio panel to the left to its off posiiion. GENERAL INFORMATION 1. Antenna-fn senera

40、l the best rsurts will be obtained by using a single wirJoutdoor antenna. It should be from 50 to 75, f.eet long including the lead-in and ground wires, which should be short and direct. A lonEer antenna will increase the sens,itivity and decrease the selectivity, while the opposite will apply to a

41、shorter antenna. The antenna should be isolated from other objects and as high as possible. It should be at right angles to electric light, traction, power, and other wire lines, and should not cross either above or below such lines. The antenna should be supported at both ends by glazed porcelain o

42、r glass insulators. The lead-in wire should pre- ferably be a continuation of the antenna wire. If ii is necessary to make a connection between the antenna and lead-in wire, or between sections of either, these joints should be securely soldered together. The lead-in wiie should be brought through t

43、he wall or window frame, and insulated by means o a porcelain tube. It is important that the antenna and lead-in should not make contact with any object except the insulators. When an outdoor antenna is used. it should be protected by means of an approved lightning arrester. RadioFans.CN 收音机爱 好者资料库

44、RadioFans.CN 收音机爱 好者资料库 IWhere the installation of an outdoor antenna is not practicable, satisfactory results may be obtained by. using lUoi SO ft of ordinary double iotton covered bell wire (No. 18 B. then slide the Radiotron in and out of its socket several times. If the operation is not yet corr

45、ected, replace each Radiotron, successively, with a new one of the proper type until the poor one is detected. If the instrument still operates improperly, examine the connections of the antenna and sround. These should all be good metallic connections free from any corrosion. 9. Service-The tests d

46、escribed above can be readily carried out, but you should look to your Victor dealer for assistance in case of trouble. Ordinarily, arrangements can be made with the dealer for a periodical inspection and test of the instrument at a reasonable price. He is capable of render- ing efficient service, and it is recommended that you take advantase of this service.
