Voltage Radio Detector Converter ·Tetrode-Tetrode
Sharp-cutoff dual tetrode designed for VHF RF-amplifier and autodyne mixer service in receiver front ends.
Sharp-cutoff dual tetrode used as a VHF RF amplifier and autodyne mixer tube.
Decar / Noval+1 10-contact base; center contact added to E9-1
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 tetrode sections; represented once under identical-section compression.
Section 2
Added approved missing second physical tetrode section; RCA specifies per-unit ratings for either plate and both units operating.
Source-dependent data
Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
