GI-41
Pulse generator triode
Description
Purpose and operating mode
GI-41 is a metal-ceramic pulse generator triode for generating and amplifying high-frequency oscillations in common-grid circuits. It is designed for short pulses with a low duty cycle and operates at frequencies up to 3000 MHz.

Construction and cooling
The indirectly heated oxide cathode uses a 6.0–6.6 V heater supply; nominal heater current is 1.3 ± 0.1 A. The tube may operate in any physical position. Natural air cooling is used, while the equipment design must maintain the permitted temperature at the metal-ceramic seals.
Key operating data
Reference pulse data include an anode voltage up to 3 kV, pulse anode current up to 2.9 A, pulse duration up to 1.5 µs and a minimum duty factor of 200. Useful pulse output is at least 1.5 kW; anode dissipation is limited to 40 W.
Selection and pre-installation checks
For replacement, compare the full GI-41 designation rather than using GI-41-1 as an automatic substitute: the two versions differ in heater current, pulse output, capacitances and rated service life. Inspect the ceramic, contact surfaces and seals before installation.
General operating principles are described in the vacuum tube article. Related devices are listed under generator and modulator tubes.
