Used EIMAC 3CX3000A7 #9144560 for sale

EIMAC 3CX3000A7 power supply is a high-voltage, high-power vacuum tube designed for radio frequency (RF) laboratories, amateur radio operators, and other high power applications. This device is capable of providing up to 3 kilowatts (KW) DC from a DC input power of up to 2800 volts. This vacuum tube is specifically designed to provide high power performance and long-term durability. It is constructed with a nickel-plated oxide coated copper anode, which is designed to reduce the risk of anode surface arcing caused by high voltages. The anode is also constructed with special geometry to reduce interference from the heater structure to the anode. Furthermore, the anode has an eclipsed shape wedged-slot profile to minimise the emission of virtual cathode motion. The device also includes a combination of regulating grids and neutralization features, which provides improved linearity over a wide range of operating conditions. This vacuum tube also includes special features that ensure low-noise levels. These include a metallized deposit on beam plates for low capacitance and a heat shield to reduce infrared radiation from the anode. 3CX3000A7 also includes a "CB" style cathode cooling system, which is designed for greater thermal efficiency and longer service life. This cooling system is protected by a replaceable steel jacket, which provides superior heat sinking. In addition, the device includes a convenient anode cap, which allows for easy access to the anode and filament connections. Overall, EIMAC 3CX3000A7 is a reliable and powerful vacuum tube designed for radio frequency (RF) laboratories, amateur radio operators, and other related applications. It is capable of providing up to 3 KW of DC power from a DC input voltage of up to 2800 volts. In addition, the device's special features and durable construction ensures reliable performance and long-term reliability.
