*"& Who Was Right? Two said they were wrong — thousands use them with a degree of satisfaction not obtained with any other kind of audio amplifying device. That is the story of S-M 220 audio transformers. Five months age when 220's were about to be offered to the public, samples were sent to all important laboratories and magazine editors. Enthusiastically favorable comment came from all but two. Two editors condemned them because they were not "perfect" insofar as the construction and design of transformers alone is considered. But there lay the very cornerstone upon which the S-M 220's and 221's were developed-they were not intended to be "perfect" alone. The dominant thought at the outset was not to build a "perfect" transformer but rather one whose characteristics, together with all the other elements that had to be considered, would render perfect tones. Existing speakers had to be considered, the short comings of broadcasting had to be compensated for and consequently the 220 is not a "perfect" transformer when used alone, but a unit which when used with ordinary loud speakers for every day broadcast reception, produces, for the whole, almost perfect reproduction. Who was right? Now after five months, thousands of transformers have been sold. Each was bought with an unheard of guarantee — that it would give better reproduction than any other type of equipment. And only two have been returned for refund! Are we to believe the two who said the transformers have to be "perfect" or the unqualified endorsement of all but two of the thousands of users? Two against thousands — who was right? You, too, can buy S-M 220 audio and 221 output transformers with the same "better than anything else you've ever heard" guarantee. The price is but $6.00 each. Do you know the secret of quality reproduction ? Have you your copy of "The Secret of Quality"? It tells you simply how to get the most out of your audio amplifier — how to get real quality. It explains just why a "perfect" amplifier is of no value — why "imperfect" speakers, transmitting stations, and compensating audio transformers, spell perfection for you. It's free!
