Voltage - Triode (single) ·Triode
Mullard directly heated triode with published ratings and characteristics. Available source material does not establish a narrower functional role confidently.
Mullard triode with published ratings and characteristics extracted from the supplied datasheet.
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.
1 physical section, each with unique specifications.
Section 1
Promoted from clearly identified printed ratings/characteristics; additional published operating points and capacitances retained in TUBE_SECTION_PARAMETER.
Source-dependent data
Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
