Douglas War drop, Editor of Radio H.rohandlatng ) MISSING (Copy for Thin Department Supplied by American Legion Neva Service.) Amplidine Circuit. By THOMAS W. BENSON The principle of neutralized tuned radio frequency amplification Is utilized In the circuit given In the attached illustration to form a receiver that is nonradiating, selective, has good range and volume and is ensy to build and operate. The most Interesting part of the circuit is the method of constructing the inductances and the source of the current used to prevent oscillations In the circuit. It will be noted that two Inductances are shown in the diagram shunted by .0005 mfd. condensers for tuning. These Inductances are termed ampllformers and are made from n honeycomb coils in the following manner : Take a coil and strip off 2 turns, then count back 15 turns on the coil and carefully raise the wire and take a tap; this tap is lettered C. Now count back 15 more turns and make another tap, B. It is not necessary to unwind the coils to take these taps. The colls are then clamped between two pieces of bakelite 2V Inches square In which have been drilled holes to mount terminal posts. 75-tu- the condensers. In mounting the coils they should be mounted at right angles to reduce any coupling between them to zero. The connection to the rest of the apparatus is made as shown in the diagram. The neutralizing condenser is a small midget variable condenser mounted on the panel. The rest of the circuit presents nothing really new. As to the theory of Its operation. The 15 turns of the first coil between G and D form an untuned primary circuit and by reason of the inverse aerial connection grounds the negative filament reducing body capacity. The condenser tunes the remainder of the first inductance which Is the grid Input to the radio frequency tube. The plate circuit of the radio frequency tube includes 15 in the second coil and forms an untuned plate circuit closely coupled to the tuned input circuit of the detector. It will be noted, however, that the portion of the coll between C and D is neither in the plate or grid circuit, but 13 closely coupled to both. The end of the coil isconnected through thestabiliz-in- g condenser to the grid of the radio frequency tube. Now should there be any tendency of the plate circuit to feed back to the grid through the tube capacity it Is neutralized by an ee,ual and opposite feed back obtained from the extra winding on the coil. Ter feet stability can be obtained by the adjustment of the stabilizing condenser. But this condenser is mounted on the panel tor a very good reason. We could mount It fixed behind the panel, but by making it adjustable a gain In volume and selectivity is obtained. It Is well known that the greater the tendency of a radio frequency amplifier to the greater the ambut the instant oscillations plification, start the amplification stops. Therefore when a signal is picked up, a slight adjustment of the stabilizing condenser is made to slightly unbalance the circuit when the signals will lie greatly strengthened and the circuit can be put right on ddge," so to speak. It would not be practical to keep the circuits in this critical condition while tuning, for the set would go into oscillation without warning, but when a station is picked up it is entirely practical to push the circuit up to the edge of oscillating, but not beyond. The receiver is remarkably easy to handle and gives results equal to any four-tub- e set built. It possesses all the stability of the neutrodyne as well as the selectivity and, in addition, permits the slight unbalancing of the superdyne and teledyne circuits that New accounts for their efficiency. York World. osc-illut- The insidaend of the coil goes to post A, the second tap made to post 15, and the first tap to post C and the outside end of the coil to tap D. The first coil does not need tap B taken out and this coil has but three terminals, A, C and D. For convenience in mounting a hole is drilled in the corner of the bakelite end pieces and a small brass angle bolted to the coil so the coils can be mounted on one of the terminals of Make Rheostat Serve in Place of Potentiometer By JULIUS PHILLIPS Wherever a potentiometer Is used there is a constant drain of current from the A battery, even when the set is not in use. This is particularly true when a potentiometer of low resistance is employed. To overcome this, an A" battery switch may be inserted in one of the filament leads to disconnect the battery from the set when not in use. This switch, however. Is not necessary and can be eliminated. Only one side of the potentiometer is connected to the battery, the other side going to one terminal of the rheostat. When the rheostat is turned to the off position, the potentiometer is The extra resistalso disconnected. ance of part of the rheostat is added to that of the potentiometer, but as this is only one or two ohms and as the rheostat Is varied very little after An Aerial of This Type Proves Very Why Use a Potentiometer Switch?
