Eimac 4CX15000A

Input network:
1:9 Transformation, 450 Ohm, 500 W HF Resistor, Tube Input Reactance Compensation & Neutralization for each Band, 11 pol. bandswitch, two levels
Output network:
Roller inductor 22 uH, Vacuum Caps: 500 pF var. 15 KV + 2500 pF var. 5 KV
Metering: Output, SWR, Plate current, Plate voltage, Screen & Grid current
Computer control of plate current (every 5 msec), SWR and all switching functions:
No relais switching under power conditions
Soft start inrush, 10 sec delay time for full power
Turbine blower with 2 speeds
Well regulated screen and grid supply for +ve and -ve currents as well as current limiting to protect the tube and minimize the IMD. It is impossible to override the screen and grid dissipation at any working conditions
The finish is of high quality black eloxial aluminia
