DW4-350 tube: datasheets and technical data
Explore available pinout, electrical data and related types for the DW4-350 vacuum tube.
The Mullard DW4-350 is a directly heated full-wave rectifier. Its sheet specifies a 4 V, 2 A filament, identifying the manufacturer-documented 4 V version without transferring data from similarly named rectifiers. The two anode sections and filament are separately listed in the connection table.
Specified limits include 2 × 350 V RMS anode AC, maximum rectified output current 120 mA and maximum capacitance 16 µF. The 2 × 350 V figure concerns the two AC branches, not a guaranteed DC output voltage. Minimum limiting resistance Rlim is listed as 0 Ω; this single entry is not expanded into a complete supply circuit. The page gives no internal voltage-drop curves or loaded DC output voltage.
The British four-pin base has an explicit assignment: pins 1 and 2 anodes, 3 and 4 filament. The manufacturer drawing is retained without assuming a viewing orientation not specified in the text. Dimensions are overall length 142 mm and overall diameter 51 mm, presented without individual maximum markings or tolerances. Both are recorded with Mullard attribution and the original page. Documentation: Mullard, DW4-350, Directly Heated Full-Wave Rectifier, Issue 1, sheet DW4-350 1054-1. No explicit publication date appears on the available page.

How to use the Valve Archive
EnryLab Valve Archive allows you to search for PDF datasheets and technical documentation by entering the exact code of a vacuum tube. Enter codes such as EL84, ECC83, 12AX7, 6L6GC, or 300B to view variants, manufacturers, and documents available in the technical archive. The search uses exact matches, thus avoiding partial or irrelevant results and making it easier to find the correct datasheet.
Datasheet PDF and frequent searches
The most searched acronyms have dedicated and indexable pages, with clean URLs and linked documentation. You can start with frequent searches to quickly consult the most used valves in the audio, radio, and technical restoration fields.
