PINT-SIZEDPOWERHOUSEI Here is Pentas new PL-6549 beam pentode,a compact power package which is daily findingnew apphcations where reliabihty, high effi-ciency at low and medium voltages, low drivingpower, and excellent linearity are required. For r-f output of 50 to 250 watts, or audiooutput up to 325 watts, the PL-6549 outclassesall other transmitting-type tubes. The beampentode construction improves linearity—pro-vides distortion-free high peak power output inaudio or linear r-f service. RATINGS
