  • New Sentinel Six.
    NEVER before in the history of radio has a two-control six-tube receiver built in a genuine
    heavy walnut cabinet been offered at this price. Never before has such a tremendous value been offered to anyone in this country. This astounding value will take the country by
    storm and this is an opportunity to buy a powerful and beautiful radio receiver of latest design, having only two tuning controls, at a price far below that which even the most mediocre of receivers has heretofore been sold.
    A beautiful and distinctive table model set which is adaptable to the finest furnished home.
    Avail yourself of our offer without delay and obtain the biggest value that has ever been known. This set will meet the strictest requirements in a long distance, selective and easy tuning receiver. The set needs no additional controls and each of the condenser controls are matched. The tuning inductances are also matched, making the logging of stations simple and easy. We have unsolicited testimonials from thousands as to the wonderful results received and the lack of care required with Columbia Receivers.

    Set Construction.
    The Sentinel 6 is built by Columbia and backed by Columbia—for years a factor in the radio manufacturing business. The panel is gold etched, finely embossed; knobs are neat for finer tuning. No vernier dials with their usual backlash. All parts mounted on sub-base. Modified straight-line frequency condensers. Three stages of low ratio audio-amplification. Bakelite sockets, solenoid coils. The latest and best features of construction are utilized in the Sentinel 6.
