Diode (NOT rectifier) ·Diode-Diode
Temperature-limited tungsten-filament double diode whose plate current is deliberately controlled by filament voltage, intended for specialized regulation, measurement, or signal-processing circuits.
Temperature-limited double diode with tungsten filament; plate current is controlled by filament voltage.
Miniature 7-contact
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
Published characteristics and ratings promoted where clearly recoverable from source.
Section 2
No fixed ratings are recorded for this section.
Second physical diode section added in approved section-structure reconciliation.
Source-dependent data
Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
