4x QQE03/12 VALVO |GU17|RS1029| UNused OpenBOX VACUUM TUBE DOUBLE BEAM TRIODE

APPLICATION
VALVO QQL03/12 mlenetec hex-
fluorine coniferous radiant tetrode with a value
power dissipated by anode
2X5 watt, with low values of inter-electrode capacitances and with internal neutralization, which is intended for use as a power amplifier of imso-frequency, as a hexerator, frequency multiplier up to 200 MHz, and, further, as a MO-duactor.
ENVELOPE.
Glass, finger-shaped with a denitashtyr*
with a denitashpin* foot on which the electrodes are carried. The screen grids of both systems are mutually connected and lead to one pin of the bottom. The middle point of the heater is led to a separate pin, which allows the use of schemes after a dovalent or paradlel power supply.
bulkhead circuits
FILAMENT CIRCUIT DATA
The cathode is oxide filament cathode; it is powered by a paracoupled or sequential circuit.
