Eimac 4CX10000D
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 20 uH & 2 motorized vacuum capacitors 500 pF / 15 KV and 2.5 nF / 5 KV
Metering: Display of all parameters – no switching
Computer control of all switching functions: No relays 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's impossible to override the screen and grid dissipation at any working conditions
The finish is of high quality black eloxial aluminia
