CONDENSER The Pioneer First patented in 1911. First publicly displayed for use in radio receivers in 1921 — and in continuous development and production since then — the Mershon Condenser is unquestionably the pioneer, practical, successful electrolytic condenser. And by virtue of the vast experience and research behind it, it is today years ahead of any other condenser in the field. It was first to provide high capacity in small space, to afford absolute freedom from puncture and to embody a service life measured in years, rather than weeks or months. 31 Manufacturers Use It as Standard Equipment The fact that 31 of the leading set manufacturers of America use Mershon Filter Condensers as standard equipment in their products, is proof of the premier position they hold in the radio field. Engineers and manufacturers, as well as experimenters— thinking solely in terms of maximum efficiency and reliability — have found in the Mershon vastly improved performance and substantial savings in space, cost and service. The new booklet "Puncture-Proof Filter Condensers" describes the Mershon Condenser, and shows how it can be effectively used in power converter equipment.
