Sprague Tel-ohmike Be Luxe
The editors of Radio Today are right! Time — sold on a profitable basis — is the essence of successful servicing. And when it comes to saving time in checking condenser or resistor troubles or doing a dozen and one other jobs around a service bench, the new De Luxe Tel-Ohmike beats anything you've ever seen. It includes a built-in voltmeter and a milliammeter with switch and pin-jacks provided so that the meters may be used for measurements external to the instrument.
Tel-Ohmike makes it easy to make complete, accurate tests of all condenser and resistor characteristics. It indicates "opens" and short-circuits — even the hard-to-find intermittent "opens." It measures leakage current and power factor; meas
ures insulation resistance up to 10,000 meg.; analyzes all condenser types at their exact working voltages; makes capacity measurements from .000010 mfd. to 10,000 meg. and resistance measurements from .5 ohms to 5. meg. Balance indications are given by a "magic eye" tube. Measurements are taken from large, direct-reading scale. See Tel-Ohmike at your jobbers, or write for folder.
De Luxe Tel-Ohmike $39.95 Net
Standard Tel-Ohmike (Without voltmeter or milliammeter, but with jack so you can plug in your own meters) $29.70 Net
After you've located a bad resistor with Tel-Ohmike — then play safe! Replace it with a Sprague Koolohm — and you know the job is done RIGHT! Koolohms cost no more than ordinary resistors, yet are outstandingly different in construction, amazingly superior in performance. Every bit of wire is insulated BEFORE it is wound with an exclusive heat-proof, moisture-resistant material. This permits layerwindings to give greater resistance in smaller size, faster heat dissipation, and permits use of larger, sturdier wire for safety. Then, to top off an already tip-top job, Koolohms are insulating from end to end and doubly protected with a peel-proof, crackproof ceramic shell containing the famous Sprague Automatic Overload Indicator.

. . . and save time and space in the bargain. Follow the lead of hundreds of successful servicemen who use Sprague Atoms for all types of dry electrolytic condenser replacements — large or small. Atoms always fit. A small stock equips you for almost any job. They've got more "guts," are more dependable than many of the larger, old-style units they replace. All capacities — voltages — single and dual combinations. Two or more Atoms may be combined by using Sprague ST Mounting Straps to give you countless hard-to-get 'special" replacements.
