RADIO BROADCAST ADVERTISER 3 VITROHM RESISTORS . IN EVERY INDUSTRY . IN EVERY LAND Vitrohm Resistor 508-2 is employed by the Thordarson Electric Mfg. Co. in their R210 Power Compact. The Resistor has a total resistance of 13,000 ohms in steps of 2000, 2000, 2000 and 7000 ohms. It is priced at $2.65. Vitrohm Resistors ^ for radio I Vitrohm Resistors are made by winding a special resistance wire upon a refractory tube and protecting both the wire and terminal contacts with fused-on vitreous enamel. This process has been used by Ward Leonard Electric Co. for more than 36 years. If Circular 507 , describing Vitrohm Radio Resistors, and "Vitrohm News" will be sent you without charge upon request. .... Equipped with VITROHM RESISTORS T JL ODAY'S electric radio receiver is a highly complex instrument placed at your service by the throw of a switch and turn of a dial. The intricacies of circuit and mechanical design probably do not interest you; it is enough that the receiver operates to your satisfaction each time it is turned "on". One criterion of probable receiver life is the quality of component parts. The resistors, for example, limit current and voltage in almost every part making up the receiver. Their failure frequently means damage to other parts. Vitrohm Resistors are most frequently chosen by those radio manufacturers who make certain that their product will serve you long and well. Vitrohm Resistors are chosen by every industry where the accurate control of current and voltage over an indefinite life is of importance. Make certain that the power supply unit in your next electric radio receiver employs them. WARD LEONARD ELECTRIC CO. 38-32-33-3 MOUNT VERNON, N.Y.
