Radio Broadcast (Nov 1926-Apr 1927)

RADIO BROADCAST ADVERTISER 333 Equamnatic has surprised them, all with its matchless DX performance "I logged 40 stations one night through powerful local barrage" Raras Electric Company, 19 So. La Salle St., Chicago, Illinois. Gentlemen: I have several sets of the most popular recent circuits, and the Karas Equamatic I just built — all distance getters of no mean ability. But for wonderful quality and unusual distance with real volume and unbelievable selectivity your Karas Equamatic has them all stopped. In one evening I logged 40 stations, including 8 of your own Chicago stations, right through a barrage of powerful New York local stations. My hat is off to you. On another evening I clocked 4 4 stations, among them some startling surprises, like WFFA, Dallas; KGO. Oakland, California, and KOA, Denver, just like a local. I held KGO for 2 5 minutes and could go back and pick theni up at will. To be located as I am, right on top of so many high powered New York stations, and filter through them all and bring in Pacific Coast stations with clarity and volume is a record of which I am truly proud. I do not believe any set but another Karas Equamatic could begin to equal it, considering quality, selectivity, distance and volume. You may use this letter any way you like if it will help to let other particular fans know what can really be accomplished when once you get hold of the REAL THING. I venture to say that if only one-tenth of the fans of the country could hear an Equamatic just once there would be a stampede of Equamatic builders and you would have such an avalanche of orders for the parts that you couldn't begin to fill them. There are too many circuits and not many good ones. Sincerely yours, Thos. F. Meagher, 7765 75th St., Glendale, L. I., New York. "For Quality, DX Selectivity and volume it caps them all" 'HEN the Karas Equamatic Five Tube Sensation was offered the public in October, 1926, we little dreamed that in a few short months it would take first place among radio receivers for distance as well as for quality of tone — for selectivity and for volume. And yet that is exactly what has occurred. Read the two letters from Equamatic builders appearing in this advertisement. Note what they say about the performance of the Equamatic. These are but two of many similar letters from our files. The tremendous success of the Karas Equamatic is due to the correct principles used in the Equamatic System— the automatic, absolutely equal transfer of energy between primary and secondary inductances at all wave length settings of the dials. This energy transfer is maintained at a continuous maximum by a principle unique in radio. In the Equamatic System the primary coils of the Equamatic Inductances are attached to the shafts of the condensers and are adjustable in their relation to both the condenser shafts and the secondary coils, while at the same time being entirely separated from the secondary coils. The latter are adjustable to any practical angle in relation to the primaries, which are automatically, constantly and continuously varied at a definite ever-changing rate of variation, with the turning of the condenser dials. This provides the necessary variation in the impedance of the inductance according to the variations in the frequency, for, since impedance varies with frequency, and energy transfer from primary to secondary varies with impedance, much more inductance is required in a primary coil to tune to 600 meters, for example, than is required to tune to 200 meters. We want you to read the two letters in this advertisement.

Send to-day for the Karas parts so you can build it without delay. KARAS ELECTRIC CO. 1062 Association Building CHICAGO Karas Electric Co., 19 So. La Salle Street, Chicago, Illinois. Gentlemen: The Equamatic is fine looking. It looks like the best ever. You surely have them all beat when it comes to good workmanship of parts. It works exactly as you say it does. Its quality is exquisitely smooth. As for DX, she is a green lizard, better by two times than any superhet I have ever built, and I have been a superhet boy for a long time. Yesterday afternoon, about 3:30, I got two Chicago stations. This is wonderful performance— to get two Chicago stations in the day time. I have to hand it to you for receiving DX broadcasts. I never heard such a radio in my life before. The quality is superb, more actual than anything I have ever had before. Karas Equamatic has every set I have ever seen licked for picking up stations, and besides gives considerably more amplification on distant stations than any set I have ever heard. Counting everything — quality, DX, selectivity and volume — this Equamatic caps them all. Very truly yours, John Wallace Gillies, 80 West 40th St., New York City.
