3CW2500C7 / YU -157

      The 3CW2500C7 / YU -157 is a rugged coaxial base power triode designed for use as a cathode driven Class AB2 or Class C amplifier. It is recommended for VHF or UHF service as a linear amplifier, power amplifier, or pulse amplifier. Linearity and power gain are both excellent due to the low ratio of grid to plate current, and the relatively high amplification factor. Low grid interception of available emission current is due to the beam forming geometry of the special grid and cathode design.
