2 X GS-9B GS9B Tube (GS-90B) Microwave Triode ??-9? 300W NIB BOX The GS-9B is physically identical to the GI-6b and GI-7b, but several electrical parameters are different,because GI-6B and GI-7B(T) tubes have been developed as a radar pulse tubes but GS-9B is designed as tube for linear amplification in microwave amplifiers in the relay microwave transmitters. . tubes classification: GI - Generator Impulse (developed for radar), GS - Generator Signal(developed for a linear amplifications) The cathode/grid area of the GI-7B is approximately double that of the GS-9B,because for big pulse current. This increased grid size is responsible for the higher GI-7B(T) tube capacitances! GI-7BT Interelectrode capacitances: input: 10-12.5 pF output: 4.2-5.0 pF transfer: 0.055-0.95 pFGS-9B Interelectrode capacitances: input: 7.2-9.6 pF output: 2.8-3.5 pF transfer at most: 0.04 pF GI-7B have higher tuning drift at 23cm The GI-7B(T) is only suitable for use at 23cm due to its lower gain, but the GS-9B with work well at both frequencies.
