Radio today (Jan-Mar 1939)

THE CONDENSER ^enaction OF 1938 . . . R« *£ ^ »*■ x* -,»» u&\ *% m & V Putting a repair bench in his store window, where all may see what goes on when a non-working radio is brought to him, has helped the service business of David Landa's Universal Radio Service, Oakland, Calif. SERVICING SETS of 1939! No wonder Sprague ATOMS — the sensational new midget dry electrolytics — broke all previous sales records in 1938! ATOMS are the smallest midgets on the market. They bring you the most honest-to-goodness features at the lowest possible cost. ATOMS build up to higher surges than any similar units. They have lower leakage and power factor. They're UNCONDITIONALLY GUARANTEED against blow-ups. They're made in more capacities than any other midgets, more voltages plus a complete assortment of dual capacity units with common negative leads. ATOMS are self-supporting — you mount 'em just like paper tubulars. You use *em for any replacement where you want real efficiency coupled with real economy. Sold singly or in handy kits of 6 or 12 units. An 8 mfd. 450 Volt ATOM lists at only 60c. A dual 8-8 mfd. lists at only $1. Think of the money you save !

The proper connection of the resistor is shown in the accompanying diagram. It is suggested that the serviceman install such a resistor in all AC-DC sets which come in for repair with either the rectifier tube or the electrolytic condenser requiring replacement. This resistor is being added to all future production of Stewart-Warner AC-DC radio receivers. REPAIR BENCH IN WINDOW INCREASES PROFITS During the twelve years he worked at other shops, David Landa noticed that an obscure repair department weakened the customer's ctonfidence and offered considerable sales resistance. So when he opened his own shop, Universal Radio Service, in Oakland, Calif., Dave placed his neat, orderly repair bench in the front of the store behind a spotlessly clean window, for the following reasons: 1. To attract attention to the shop by supplying so-called "action display." This decision was made after observing window shoppers' reaction to action displays and demonstrations. 2. People could see that there was neither mystery nor secrecy to repair work, but that it involved certain definite operations, all of which take time. 3. To individualize the shop and fix its location and business definitely in radio owners' minds. With a clean radio bench in plain sight, and a service man at work, a definite picture is presented that the window shopper recalls when his radio needs repair. 4. To remove any poor impressions set up by shops with unsightly work benches and test panels. Also to create more confidence in the shop and to elevate the trade to a higher level. 5. To make it possible for the customer who waited for a repair job to see that the many tests and operations required much time — this to remove objections for charges that might otherwise seem excessive. The "experiment" is no longer that; it is a proven fact that such a "work window" is a powerful magnet for service sales. Jaivette Tlotaru Converters FOR CONVERTING D.C.
