T HE TUBES ARE DESIGNED TO DELIVER A MINIMUM OF THREE WATTS OF DRIVE POWER TO THE RCA-6884 over a frequency range of 30-76 mc with an input power of 50 milliwatts. The objectives were attained with the recently annou ced tube type RCA-7801, the specifications for which were rele sed in Janu ry 1961.
