CPI 4PR60C

The 4PR60C/8252W is intended for pulse modulator service in circuits employing inductive or
resistive loads. This tube unilaterally replaces the
715C, the 5D21 and the 4PR60B/8252. The internal
structure of the tube has been strengthened to
minimize the effects of shock and vibration. The
4PR60C/8252W has a maximum plate dissipation
rating of 60 watts, and is cooled by radiation and
convection, and delivers pulse output power in the
region of 300 kW with less than one kW of pulse
driving power.
