This transformer, which carries a one year’s guarantee, is made in several ratios-2-1, 34-1, 5-1, and 9 to 1, and retails at the reasonable figure of 15s, A new variable condenser from the same factory is 2 commendable piece of workmauship, and up-to-date in every sense. The whole of the brasswork is actually silver-plated, giving a highly desirable effect for a smart receiver. Another good feature is the independent spindle-standard jin., by the way-which can be removed by loosening a screw, so that any number of condensers may readily be gauged on a2 common spindle. An efficient pigtail cuts out any chance of intermittent ‘connection. The .0005 capacity retails at 14s., and .00035 and .00025 at 138s. 6d. each. Another product is a non-micro-phonie spring valve socket, known as the "AW.A, non-microphonic." This is made of bakelite, in two patterns, the ordinary: at 3s. and the sub-panel at 2s. 3d.
