Harmonic Output 50 dB below rated output
IMD 32 dB or better
Tube Eimac 4CX3000A
Input network 1:4 Transformation, 200 Ohm, 200 W RF Resistor, Tube Input Reactance Compensation & Neutralization for each Band
Output network Switched inductor 18 uH, Caps: 150 pF var. / 9.0 KV + 330 / 150 pF fixed + 1000pF var. / 3.5 KV + 680 pF fixed
Computer control 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.
