RADIO BROADCAST ADVERTISER 305 Which do you want or Music? WHEN you have read this advertisement you will realize that an important forward stride has been made in radio reproduction and you will be glad to have learned that, no matter what kind, make or age of set you have, you can now convert it in a few minutes time and at small expense into the most perfect reproduction known to radio. In test after test under all conditions, before laboratory experts, set manufacturers, broadcasting artists of national fame, musical critics, and in test by the radio public itself, the new Truphonic amplifying principle has definitely proved itself to be superior to all other methods of reproduction — barring none. And the Truphonic furthermore has the unique feature that it can be instantly attached to any set. What the Truphonic is The Truphonic is simply this: A compact instrument containing three stages of Truphonic coupling and an output unit to protect the loudspeaker from the powerful Truphonic output. A 6 foot battery cord contains all wires to the "A" and "B" batteries (including wires for "C" battery and additional "B" battery if power tube is used). A single wire with clip attached slips over the plate prong of the detector tube which is then reinserted in the socket of the set. It is as simple as ABC and can be attached by anyone in less than 5 minutes without any knowledge of radio. Used in commercial sets Although Truphonic amplification has been on the market only a short time it is now used in the sets of 22 radio manufacturers. Unfortunately it was not perfected in time for general use by manufacturers of large production this year. Next year the trend will be toward Truphonic amplification. But if you want the most beautiful reproduction of music and speech in your home right now, get the Truphonic at your dealer's, attach it, and know that you have the finest reproduction obtainable — no matter how much you can afford to pay. If your dealer has not stocked the Truphonic we will send you one C. O. D. on 5-day money back trial. No Truphonic sent unless you give your dealer's name and address.
