Radio Broadcast (May 1928-Apr 1929)

RADIO BROADCAST ADVERTISER 181 SM Leadership means 'actio N four short years Silver-Marshall, Inc. has forged up from obscurity to the position of dominant leadership in the radio parts and kit field — interesting, you say, but just what does that mean to you? S-M leadership means just one thing — better radio for less money. Ask any one of the thousands upon thousands who enjoy radio to the full thru S-M kits and circuits. Ask the multitude of experimenters who have literally used and recommended S-M into first place; who two years ago swept S-M audio transformers into unquestioned leadership thru a veritable avalanche of approving purchases and who have held S-M audios at the top ever since. Ask the thousand odd Authorized S-M Service Stations who have built a profitable business and satisfied customers on S-M stability and worth. Or ask the dealers and jobbers who have seen S-M rapidly crowd competitors from their shelves, to become in four seasons the largest selling, most profitable parts line. They'll all tell you that S-M leadership means better radio at less cost. And S-M will lead again in 1928 and 1929 by giving you new developments that enable made-to-order or home-built radio sets to equal in external finish the finest factory productions, parts that place the performance of such sets utterly beyond competition, and, thru knock-down kits, radio receivers that will consistently and positively outperform all ready-made sets at anywhere near their amazingly low prices.
