RADIO BROADCAST ADVERTISER 689 RAYTHEON T/re Mtz^ perfects the B-eliminator RAYTHEON is more than the name of a new type rectifier. It is the symbol of a research laboratory, the mark of an organization of engineers. Radio manufacturers, radio editors and radio dealers appreciate the value of Full Wave Rectification, No Filament, No Chemicals, Ample Voltage and a Sixty Milliampere output. Price six dollars.

RAYTHEON MANUFACTURING COMPANY Cambridge, Massachusetts Why Eliminators! by ROLAND R BEERS THE outstanding difference between receivers that grace American homes to-day and those of ante-quality days lies in the naturalness of the reproduction now possible. It seems to be the tendencyamongall reputable manufacturers to improve the audiofrequency amplifiers in their receivers to the greatest possible degree, and those who build receivers at home are not far behind. Regardless of the type of amplification employed, whether transformer-, resistance-, or impedancecoupled, there are a number of claims made upon the B voltage supply that cannot be slighted or overlooked. One is an unfailing source of voltage, and for high quality reception with plenty of volume, high voltage is required. This voltage must be a quiet voltage, not full of noises or variations or flutters that annoy the listener. In other words, the B voltage supply is a sort of silent partner, always supplying his share of what is necessary in the form of power. One of the important developments in the realm of high quality reproduction has been the Raytheon tube which, with accessory apparatus, takes current from your house lighting system, converts it to a voltage sufficiently high to operate the new semi-power or power 86% Raytheon^ Tested and approved by Radio Broadcast -fc
