GU-19-1
Double beam generator tetrode
Description
Purpose and application
GU-19-1 is a double beam generator tetrode for modulators, frequency multipliers, power amplifiers and oscillators operating up to 500 MHz. It is an electronic component for dedicated RF equipment, not a replacement for an ordinary receiving tube.

Construction
The tube has a glass baseless envelope, a common indirectly heated oxide cathode, eight lower leads and two upper anode leads. The heater sections can be connected in parallel or in series; the connection is chosen only for the circuit of the equipment.
Operating data
With parallel heater connection the nominal voltage is 6.3 V and current is 1.7 ± 0.2 A; with series connection the values are 12.6 V and 0.85 ± 0.1 A. Rated anode voltage is 350 V, screen-grid voltage is 250 V and transconductance is at least 4 mA/V.
Cooling and selection
Natural cooling is used. Before ordering or installing, compare the complete designation, lead arrangement, heater connection and operating mode with the circuit and passport for the offered unit. Related RF tubes are shown in the generator and modulator tube section.
Vacuum device construction is outlined in the vacuum tube reference article. Related products are listed under generator and modulator tubes.
