Radio Broadcast (May 1928-Apr 1929)

31 S RADIO BROADCAST ADVERTISER IF YOU DON'T LIKE THE BRUTAL TRUTH — better not read this page! Silver-Marshall unconditionally guarantees the new S-M Clough system audio transformers to give greater amplification, much finer tone, and far less distortion than any standard transformers made by any other American transformer manufacturer. Contrast this straight-from-the-shoulder guarantee with the advertising phrases used by other manufacturers — not one dares offer the guarantee that S-M has given for two consecutive years — ever since the first 220 transformers were produced. And with impartial comparative tests S-M engineers have been demonstrating to thousands that the new 223, 225, 226, 255, and 256 transformers are far superior to any and all other makes. Naturally, not all fans have been able to attend S-M demonstrations at the R.M.A. Trade Show and in the larger cities. It is perhaps hard for you, satisfied as you may be with the audio equipment you have been using, to believe that any transformers can be as far ahead of all other types as are the new S-M's. So we can only say to you: "Buy a pair of 225 and 226's, or a pair of 255 and 256's; hook them up and test them. Then, if you're not satisfied that they are better than anything you've ever heard, return them to the factory for full credit." The fan unwilling to accept such an offer and who says, "The old stuff I'm using satisfies me" must simply be a man opposed to progress, content to stand still, and it is not to him that S-M appeals. But the openminded and progressive fan, ever seeking something better and finer, will find in the new S-M transformers a quality of reproduction beyond his fondest expectations. Take the case of the manufacturer of America's most expensive high-class sets, seeking the best possible audio amplification for an ultra-fine receiver. After testing all standard high grade transformers, this manufacturer's engineering staff went on record with the statement that S-M's large and small transformers are the finest of all transformers they had ever tested over a period of fifteen years! Or consider the case of the chief engineer of the largest independent manufacturer of theatre and auditorium amplifying systems, a man who has tested and analyzed all standard audio transformers — and finally selected the new S-M audios as the most perfect known audio system. Men who know, not guess, all acknowledge the supremacy of S-M audio transformers. This is a strong statement to make, but we back it up with a guarantee such as no other manufacturer has ever offered for audio transformer equipment. We dislike to tread upon the sensitive toes of other transformer manufacturers, but we know what the new S-M audios will do. And so do these other manufacturers! One of them recently approached us. "Look here," he said in substance, "we're both making audio transformers. Let's be friendly. We're not going to say anything about hysteretic distortion in our advertising, and we wish you wouldn't make an issue of it." But S-M is neither to be cajoled nor threatened. For the first time in the history of commercial audio transformer design, Silver-Marshall has eliminated hysteretic distortion, and the new S-M transformers give a sharpness and definition to bass and treble alike such as has never been known before. Do you remember when transformer "curves" used to climb "way up in the air"? Maybe you've noticed that most manufacturers are now advertising audio transformers with a high frequency cut-off. Two years ago S-M was first to introduce this feature. At first scoffed at by other manufacturers, it was eventually adopted by practically all! Two years ago S-M also introduced the first really large models of audio transformers — -a feature which more and more competing manufacturers have copied of late. And in the new Clough system under which the 223, 225, 226, 255 and 256 transformers are made S-M has again introduced revolutionary improvements just two years ahead. When you buy S-M audio transformers, you're getting the best — S-M unconditionally guarantees this to you in a straight-from-the-shoulder way that no other manufacturers have ever dared to adopt. No matter what audio transformers you have or are using, S-M guarantees you better results with the new 223, 225. 226, 255 and 256 models. For the finest possible tone, the new S-M 225 first stage and 226 second stage types at $9.00 each are utterly unequaled. Their two stage curve is shown at E, with its rising bass characteristics and 5,000 cycle anti-hiss cut-off. The two smaller types, S-M 255 first stage and 256 second stage, are unconditionally guaranteed finer than all other types on the market, and give the curve D — see how much better they are than three sets of standard competitive eight and ten dollar types, shown at A, B, and C under the same operating conditions. At the S-M factory there is always in operation a comparison amplifier. If you're in Chicago, ask to have your favorite transformers compared against the new S-M's — then they'll be your favorites. Remember — all other transformers give hysteretic distortion — only the new S-M's are free from it. Other outstanding values in new S-M kits, parts, and accessories are illustrated and described on the pages that follow.
