This never been used, from the old stock.

Generator tetrode GU-84B in cermet design with indirect cathode oxide cathode and external anode with forced air cooling.

It is used in radio engineering devices of stationary and mobile equipment, and is intended for power amplification in systems with distributed amplification systems, as well as for amplification of a single-band signal.

Main technical parameters of the GU-84B:

Tension voltage, V
27
Current heating, А 3,4-4,0
The bias voltage is negative (at Ua = 750 V, Uc2 = 375 V, Ia = 2000 mA), V
10-50
The closing voltage on the first grid (at Ua = 2000 V, Uc2 = 375 V, Ia = 20 mA), V
<150
Zero anode current (at Ua = 250 V, Uc2 = 375 V, Uc1 = 0 V), A
3,5-6
The reverse current of the first grid (at Ua = 1000 V, Uc2 = 375 V, Ia = 2000 mA), microA
80
The current of the second grid (with Ua = 750 V, Uc2 = 375 V, Ia = 2000 mA), mA/V 25 ± 60
The slope of the characteristic (at Ua = 750 V, Uc2 = 375 V, Ia=2000 mA), vA/V 44-72
Output power, kW
- in the class AB mode at a frequency of 0.1 - 1 MHz not less than 1,5
- in Class B mode at a frequency of 250 MHz not more than 1,2
