GI-7B vacuum Tube. New in Box. HF-VHF-UHF POWER COAXIAL TRIODE The GI-7B (GI-70B) microwave triode operates as an oscillator and an amplifier in continuous-wave or pulsed mode with anode modulation in the centimetric and decimetric wavelength ranges. The GI-7B with a heat sink and the GI-70B with no heat sink. The tubes GI6b, GI7b, GI7bt, GI70b and GI70bt are all the same GI7b. GI7b and GI7bt are completed by factory with coolers(HgAl) and the others (#70) without. See Dentron MLA-2500 Conversion Project, But not need sockets for GI-7B tubes,hi Click on picture: See also Dentron GLA-1000 conversion,nice project. Click on picture: Two GI-7B tubes witch 1500V anode plate give output power more 800 W on 1.8-432 MHz! The Amplifier has the simplest scheme. For GI-7B usually is not need Socket. For frequencies below 500 MHz,tube is simply inserted the Grid in metal of body PA These are coaxial microwave tubes are capable to generate on VHF. Any spurious capacitances, inductances and resistances imported Socket can cause it. Russian electronic industry interposed these tubes directly into devices. And it was the best solution! TWO NEW GI-7B tubes. Each tube in factory box. (please look at our rules and privacy policy) |
