The Talking Machine World, New York, June, 1928 R-B-M OLTAGE REGULATOR List Price $10 00 SLIGHTLY HIGHER WEST OF THE ROCKIES 25 CYCLE TYPE $12.50 IN ORDER to obtain 100% results in the way of tone quality, volume, distance, and even more important than this, to get satisfactory life out of A.C. tubes, an R-B-M VOLTAGE REGULATOR is an absolute necessity on every A.C. set. This device is guaranteed to deliver the correct voltage to your set regardless of your line voltage, the make of your set, or the number of A.C. tubes that it uses. It is small, compact, beautifully finished, and attaches to your radio set in just a few seconds' time. It does not require the use of any tools or the connecting of any wires, other than plugging it into the light socket. No rheostats or voltmeters required with this device. It does not waste or consume any current, nor heat up. How it works The R-B-M VOLTAGE REGULATOR will deliver 110 volts to your A.C. set no matter whether your line voltage is 90 volts or 130 volts or at some point in between. By delivering the proper voltage at all times to your set, it will give you the maximum efficiency in the operation of your receiver since it will always burn your A.C. tubes at the voltage for which they were designed to give the best results. In districts where the line voltage is exceedingly high, it will prolong the life of your A.C. tubes to their rated number of hours. On the other hand, where the R-B-M MANUFACTURING CO. Logansport, Indiana line voltage runs as low as 90 volts, this device enables you to get all of the kick and volume out of your set because it will boost the voltage up to the right point for which the set was designed, viz.: 110 volts. Thus you never have to worry about ruined reception due to low voltage which is very common in many districts. Sell it over the counter Think what it means when one of your customers comes in with a burned out A.C. tube. Immediately you sell him this device right over the counter. Your customer can install it just as efficiently as you can. It does not require the use of a service man, voltmeter, or any tools to install it. Once set for the proper voltage there is nothing to get out of order. You not only make a profit on the sale of this device but it means satisfied customers and no more free service calls due to burned out A.C. tubes. The R-B-M VOLTAGE REGULATOR is fully covered by patent applications. DEALERS: If your jobber cannot supply you with R-B-M VOLTAGE REGULATORS, write us direct.
