r RCA-2CW4, 6CW4, 13CW4 High-Mu Nuvistor Triodes RCA-2CW4, 6CW4, and 13CW4 are high-mu triodes of the nuvistor type, intended for use as grounded-cathode, neutralized rf-amplifier tubes. The 2CW4 and 6CW4 are particularly useful in vhf tuners of television and FM receIvers. The 13CW4 is designed especially for use in antennaplex and antenna-system booster amplifiers. In these applications the tubes provide exceptional performance in fringe areas and other locations where signal levels

The regIon of permissible oper­ ation is bounded by the lines representing plate dissipation = 1.5 watts, plate voltage = 135 volts, and plate current = 15 milliamperes. In class Al amplifier service, because no grid current flows, the plate current rating IS equivalent to the cathode current rating. To determine the required minimum series plate-circuit resistance for a given set of o~rating conditions: 1. From Fig.2, Averag
