Vf 7 Volts / If 1.8 Ampere / Direct |
Description |
Transmitting Triode, air cooled with tungsten cathode and tantalum anode.
Grid and anode from side connections.
The tube is intended for operating as a generator of high frequency at ultra-short wavelengths not lower than 3.5 m (or at a frequency not higher than 86 MHz).
At anode voltage of Va = 700 V, the ГУ-4 tube could give up to 4 W of useful oscillating power.
When using the tube in different modes of operation, the anode dissipation power must not exceed 15 W.
A date code showing month and year of manufacture is shown on these tubes.
