By CAPT. H. DE A. DONISTHORPE The following Is a description of a simple amplifier for magnifying oscillations of audio frequency, and is simple by virtue of the fact that no intertube transformers are employed.

The plan of connections of this circuit is shown in the dingram, and the actual arrangement is, of course, Senators Sons Are Newsies used in conjunction with some form of tuner, the low frequency and rectified signals for amplification being led Into the amplifier at the Input terminals A or B. Resistances 1, 2 and 3 are of a high value and should be of the same order as the effective Internal resistance of the tubes employed, which ranges usually about 50,000 ohms. The resistances 4 and 5 should be about 200,000 ohms each, but this value Is not so critical as that of re- The president of three corporations engaged in manufacturing and marketing the children of her fertile brain, the inventor of more than two score unique devices, 33 of which have been patented, Miss Beulah Louise Henry, formerly of Memphis, Tenn., but now a resident of New York, finds time to make her own hats, sew, embroider and to make a happy home of the apartment in which she lives with her mother, who is a daughter of the late Governor Ilolden of North Carolina. The Lady Edison, as her friends call her, is possessed, in the words of Garrett I. Serviss, the scientist, of a rare gift in being able to translate vibratory Impressions from one form to another. sistances 1, 2 and 3. These resistances can be of any type, such as composition rods, or, then again, they may be made of resistance wire, but if this latter form Is to be used it Is necessary to wind the same so that there is no inductance effect. Where a rod resistance Is resorted to particular attention must be paid to the method of connecting same to the rest of the circuit to insure good contact, otherwise parasitic noises will result w hen the Instrument is put Into operation.

This circuit will operate almost any type of loud speaker with wonderful volume on any local station within It Is even possible to put over loud speaker reception with stations 1,500 miles distant. The circuit is not only extremely sensitive hut wonderfully selective. The best results are obtained by using UY201A tubes. Following several valuable suggestions these Improvements in the circuit are advised: Recently a variometer was used in the plate circuit to produce regeneration. A much snappier action may be obtained by using a standard varloe type preferred. coupler, the The rotor winding need not be changed, as the average varlocoupler has a sufficient number of turns to produce regeneration over the frequency used in the music band. 30 miles of New York. multi-audl-ple- By LEON BISHOP Procure any standard make of varlocoupler, rewind the stator with 50 turns of No. 20 double cotton covered magnet wire. At a point eight turns from the ground side of the stator take off a tap which goes to the antenna. Across this coil connect a .0005 variable condenser. This condenser must not be over .0005 in capacity, but under that value if anything. The grid condenser has a capacity of .00025 mfd. and the grid leak a resistance of 3 megohms. The bypass condenser Is .002 mfd. The audio frequency amplifying transformer may be high ratio types. any of the The first or detector tube rheostat should have a resistance of 30 ohms, while that of the second or amplifying rheostat should be 10 ohms. The detector tube B battery voltage Is variable from 22 to 34 volts. It Is Important that the outside windings of the secondary on the audio frequency transformer be connected to the grid, and that the inner side of the secondary shall be connected to the negative side of the A battery, and not to the negative side of the filament. This circuit, when working properly, will not only regenerate but will have a tendency to spill over when rotor e King of Rumania Visits England become stator.

The manner In which the amplifier operates may then be briefly described as follows: The Incoming oscillations produce a difference of potential between the grid and filament of the first tube, which, in turn, produces voltage drops across the resistances 1 and 2. The condensers 4 and 5 then permit these voltage variations In the resistances to be applied directly across the grids and filuments of the second and third tubes, bringing about magnified currents in the anode circuits after the usual thermionic tube theory. These condensers serve a secondary and prevent purpose simultaneously the establishment of a permanent voltage due to the B battery being Impressed across the grids and filaments of the tubes. The third condenser, 0, Is ingeniously Inserted to prevent a direct current of the B" battery passing through the telephones, which would result In the same being impaired by the permanent magnets becoming demagnetized. The high resistances, 7 and 8, it will be seen, are connected directly to the grid of the second and third tubes through to the negative pole of the A" battery and serve as leaks." In this manner an accumulation of negative electrons on the grids is not permitted; this effect, if not remedied, would, of course, result in the electronic emission from the filaments being arrested owing to the accumulated negative charge. This Instrument will be found to produce quite excellent results, providing care be taken in the selection f resistances, although it cannot be said that the amplification so obtained Is equal to that of an intertube transformer arrangement. It will be necessary to regulate the filaments current carefully in order to obtain the best results, and the best condition of sensitiveness will make Itself apparent when a tap of the first tube results In a microphonlc effect in the telephones.

This eliminates a tremendous amount of code Interference, and It will be easily possible to listen to tlie shorter wave stations, even through the local Interference of station WEAF. It must be remembered when using the type of varlocoupler that It may be necessary to reverse the connections to the rotor. When the proper connections are obtained and the rotor Is turned parallel to the stator winding, a terrific screech should he heard In the phones. In other words, the best point of tuning Is arrived at with the rotor at about right angles to the stator. New York Herald.
