Input network:
50 Ohm, 100 W HF Resistor, 5 pol. Chebychev Low Pass Filter
Output network:
Roller inductor 21 uH & 2 motorized vacuum capacitors 500 pF / 5 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, 200 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
