CASE SEVENTY
LINE
OVER-ALL POWER
THIS year the buying radio public will be satisfied with nothing less than the outstanding performance in radio receivers, that has been repeatedly promised, but seldom fulfilled.
In the new "Seventy" line, Case engineers have created a radio set that definitely embodies the essential factors necessary to meet this consumer demand.
The famous Hazeltine Neutrodyne principle as the basis, with access to the hundreds of radio patents under which we are licensed by R. C. A., Hazeltine, Latour and others, gives the new Case "Seventy" a remarkable advantage.
The factors of sensitivity, selectivity and volume in this set are so correlated as to produce a sum total of power that definitely results in performance needed to satisfactorily cope with present-day broadcast conditions. Add to this a range of decidedly popular prices, a distinct appeal to the eye in furniture value, and to the ear in tone quality. Immediate and lasting success is inevitable.
The engineering formula, O. A. P. (Over-All Power) which is here given for the first time, will have a vital bearing on radio merchandising hereafter, as the means of conveying in unmistakable terms, the relative efficiency of radio receivers.
Thus, the Case Radio staff not only contributes the remarkable "Seventy" line, but also has the distinction of conceiving and presenting the term, O. A. P., as a fair standard of measurement of the actual value and efficiency of a radio receiver.
It is our claim that the Case "Seventy" line will be the invariable choice of everyone who is governed by the rigid comparative tests which O. A. P. exacts.
