The
4CX15000A vacuum tube is intended for use in audio or radio
frequency applications. It features a new type of internal
mechanical structure which results in higher efficiency. Low RF
losses in this mechanical structure permit operation of the
4CX15000A at full rating up to 110MHz, and at reduced ratings, to
225 MHz.
