Na-ald Sockets are moulded of Bakelite with uniform cross-section and cure, and other engineering features incorporated to avoid plate to grid losses and to insure that each tube develops its fullest efficiency. The new Na-ald dials combine rare beauty of design with highest efficiency in use. These dials are moulded from genuine Condensite in such a way that absorption losses are reduced to a minimum. Knobs are so shaped that fingers do not conceal clear numerals and graduation on the bevel of Na-ald dials.
