Radio Broadcast (May 1929-Apr 1930)

-RADIO BROADCAST ADVERTISER. XT How Somers Sells Satisfaction in Custom Receivers F. B. SOMERS, General Merchandise Saginaw, Michigan Silver-Marshall, Inc., Chicago A short time ago I built a set for a man who wanted "something good." From my experience with S-M kits I ordered the complete outfit, 712 tuner, 677 amplifier, and the 851 speaker. I just delivered the set and I think I have "hung up" something for the "other fellow" to shoot at. At night I could register a station on every frequency in the broadcast band. Between nine and ten in the morning I tuned in WGY, WEAF, WCCO, WOC, KTNT, KMBC, WFAA, and WBAP. The last named is a little more than 1 100 miles air line from Saginaw. This did not "just happen," as I repeated it several times and you could not tell the distant station from the nearer one by the volume. I have built, remodeled and repaired hundreds of radios, including ten-tube supers, and this 712 is the first one to give me a real thrill. I am going to build one for myself now. — F. B. Somers. The all-electric S-M 712 Tuner, with band-filter and power detector, stands far beyond competition regardless of price. It uses 3 — '24 tubes and 1 — '27. Price only $64.90, wired, less tubes, in shielding cabinet shown. Component parts total $40.90. The new S-M 677 forms a perfect power supply, as well as an audio amplifier of appropriate superior quality, for use with the 712, or for records. Special input transformer has high ratio, ideal for phonograph pickup. Tubes required: 1 — '27, 2— '45, 1— '80. Power comes from any 105 to 120 volt, 60 to 50 cycle source. Wired complete, less tubes $58.50. Component parts total $43.40. (For 25-40 cycle current S-M 67725 costs $72.50 wired.)
