Voltage Dual Tetrode ·Tetrode-Tetrode
Directly heated dual electrometric tetrode for low-current measuring devices.
General specifications
Properties common to every published source and operating point.
Electrical assignments shared by every tube using this base designation.
No verified pinout is recorded for this base designation.
2 physical sections, each with unique specifications.
Section 1
Russian 2EE2P first physical electrometric tetrode of directly heated dual-tetrode measuring device, using shared oxide-coated 2 V, 55 mA filament (50–60 mA specified range) and published gain 1.3. Derived specification lists typical anode 6 V, current 0.045 A, transconductance 22.5 mA/V (15–30 mA/V specified range) and grid figures +4 V / -3 V. Such currents, conductance units and grid assignment are uncertain for an electrometric device; do not promote transconductance, current maxima or voltage maxima without original-source verification. Section index corrected 0 to 1.
Section 2
Russian 2EE2P second physical electrometric tetrode of directly heated dual-tetrode measuring device. Shared oxide-coated filament 2 V, 55 mA (50–60 mA range), gain 1.3. Derived summary lists typical anode voltage 6 V, anode current 0.045 A, transconductance 22.5 mA/V (range 15–30 mA/V), with control/screen grid figures 4 V and -3 V; units and electrode allocation are questionable for electrometric operation and require independent manufacturer verification. No numerical maximum voltage or transconductance values promoted. Second physical section index standardized to 2.
Source-dependent data
Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
