Diode (NOT rectifier) ·Diode-Diode
Indirectly heated dual diode designed for detector, phase-comparator, and rectifier service, with useful high-frequency operation to roughly 700 MHz.
Indirectly heated dual diode intended for detector and phase-comparator service.
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
Two identical diode systems; representative row. Peak inverse voltage is 420 V; total anode dissipation is 0.5 W for both systems.
Section 2
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.
