Absolutely similar GI-7B tube. Save!


See 1kW 50MHz PA on 3xGI-6B tubes: Made in Japan

With its 350 Watts plate dissipation this tube is a good choice for producing medium power (300 to 500 Watts). At a plate potential of 2000 Volts the gain is around 13 dB and the efficiency about 60% on 144MHz when build in grounded grid. A 432 MHz version with a half wave-line will give an efficiency of about 50% when build in built in grounded-grid style.

The GI6b (LD6) is also good on 23cm. In grounded-grid style with 3/4-wave coaxial-tank, at a plate potential of 1500V and Ia= 300...350mA. The pwr gain is still around 12...13 dB or more. The efficiency is same as with 70cm configuration or around 50%. With a good matching in the cathode circuit only 10...15W of drive is needed.

Equivalent types : The tubes GI7B, GI7BT, GI70B and GI70BT and LD7 (German=LD7 at WWII time).

This sale is for  TWO (2)  GI-6B new tubes. Each tube in the factory box.
