| Introduction | The linear operates with one 4cx5000a/8170 tube, in Class AB1 with a plate dissipation of 6000 watts.Class AB1 amplifiers are roughly 60% efficient. The zero-signal anode-current in a Class AB1 amplifier is normally set to about 20% of the maximum-signal single-tone anode-current. In a typical HF amplifier, the drive power required for Class AB1 operation is roughly 1% to 2% of the output power. Most of the tubes that are used in Class AB1 RF amplifier service are tetrodes and pentodes--devices that have the advantage of grid-to-screen amplification. Constructed primarily for military communication, this tube is physically and electrically exceptional rugged and with additional sophisticated protection circuitry incorporated, the linear is almost indestructible. The 4cx5000a/8170 tube is a compact high slope and when operated under normal conditions, will last a very long time. |
