848-j RADIO BROADCAST ADVERTISER Supereflex Means MORE POWER PER TUBE Erla Supereflex makes tubes do triple duty. One tube actually does the work of three that would be needed otherwise. Three tubes do the work of five, unquestionably! That is why simple, compact, inexpensive Erla Supereflex receivers equal or surpass the performance of costliest, temperamental multistage radio sets. More power, tube for tube, is basic in Erla Supereflex. Nothing else can "make up for it." Greater power in Erla Supereflex just simply means finer radio, which you can afford. For you yourself can confidently build these matchless Erla circuits with Erla Supereflex CIR-KIT. CIR-KIT is a complete array of Erla Scientific Precision Apparatus, especially created to make Supereflex possible. CIR- KIT provides clear, simple instructions for perfect assembly. Blueprints are full size. The panel is pre-drilled for you. The baseboard is marked to locate every unit accurately. The famous Erla Solderless Connectors do away with soldering entirely . With screwdriver, pliers and CIR-KIT you are sure of a set that will make you proud, both for appearance and performance. The cost is very moderate. Yet the range, volume, selectivity AND TONE PURITY are rarely equaled at any price, because Supereflex does give you more power, tube for tube.
