New Sound Head From Nationa Using Carl Zeiss objective lens for a new lens system, National Sound Systems has developed a new sound head for projectors. The lens system is said to be based on a new principle which elimininates condensers and slits or apertures. A simple converter in conjunction with the objective lens takes light from any source and of any shape filament, states iNational. Should recording be improved sufficiently to warrant, the beam may be narrowed to .0005 by exchange of converter, which consists of an optical-glass ground lens mounted in a holder. The sound head, just developed, has a two-stage resistance coupled unit head amplifier with two 226 tubes and integral assembly, completely mounted sponge rubber. National states the amplifier is licensed by Vreeland Corp.
