UxX280 is a new full-wave rectifier tube delivering up to 300 volts at 125 milli-amperes, for use in cirenits specially designed for it, as it is a hotcathode type, intended for use in complete A.C. socket operation. Several American broadcast stations are now licensed for daylight hours only, and some others are authorised to use higher power before 7 p.m. The power of many large stations has been reduced, and the average for the whole 700 stations is 645 watts. The majority range between 100 and 500 watts.
