. QST . For instance, look at the Barker &Williamson 5100 in this picture. Known throughout the bandsfor the authoritative signal itpacks, this transmitter uses twoRCA-6l46s in parallel in thefinal—and two more RCA-6l46s in the class AB modulator. Here are basic reasons whyleading amateurs —and commer-cial designers like B&W—specifyRCA. RCA power tubes make itpracticable to get any power youwant—at relatively low plate volt-age. RCA power tubes are builtto handle peak plate loads withease—have tremendous reserveemission. RCA power tubes areeconomical in service! You can get RCA high-perve-ance
