IRVINGTON NEW JERSEY HIGH STANDARD UNITS With the idea of having radio enthusiasts add steadily to their equipment in proportion as their knowledge and buying power increases, the Essex Radio Service, Newark, N. J., has developed a series of quality units. The first is their " Type R " Tuner, with a range of from one hundred and fifty to twenty-five hundred meters. No variable condenser is necessary with this tuner, but there is a secondary variable condenser, in conjunction with a secondary load, which together give sharp tuning in the secondary circuit. Another instrument manufactured by the Essex Radio Service is a combination of the Type R Tuner with an audion detector, making a complete receiving set, for use with ear phones. For those already possessing a tuner, the company has designed an audion bulb detector and a two-stage amplifier, which can be used with a loud speaker. The two-stage amplifier is also made separate. The fifth instrument which the Essex Radio Service makes is a combined tuner, detector, and two-stage amplifier. All the instruments are made of quartered oak in dark mission finish, with condensite panels, nickeled binding posts and standard easily adjustable dials. LARGER PRODUCTION FOR BALDWIN'S The Baldwin Telephone Company of Salt Lake City has incorporated for $1,000,000, and will construct a factory capable of turning out from 1,000 to 3,000 head sets per day in the very near future. It is said that the present production of the Baldwin phone is not over 150 sets per day, due to the desire of Nathaniel Baldwin to produce a carefully-made, personally inspected head set. Those who know will agree that the Baldwin phone is really one of the best for radio purposes. EVOLVE TRANSFORMER The result of six months of steady experimentation, the Acme Apparatus Company announce their new Radio Frequency Transformer. It is workman-like in appearance, and the manufacturers feel that they have produced the best transformer for wave lengths of 150 to 500 meters. This transformer, they declare, is worthy of its predecessor, the Acme Audio Frequency Transformer A-Z. The Acme Apparatus Co. have been making Radio apparatus since April, 1919.
