UX-4P socket for direct heating triode such as 300B/2A3
The UX-4P is compatible with directly heated triodes such as 300B and 2A3.output tubeThis is a tube socket compatible with. Accurately corresponds to the UX-4P bass shape widely used in classic tube amplifiers such as 45, 83, 811A, WE274A, etc.output tubeIt is designed to bring out the stable performance of.
Installation dimensions and compatible vacuum tubes
The mounting hole diameter is 30mm, and the mounting screw spacing is 38.2mm.
Compatible vacuum tubes are UX-4P base such as 300B, 2A3, 45, 83, 811A, WE274A.output tubeand a rectifier tube.
Reliable retention and high insulation due to fluororesin machined structure
The socket body is made of fluororesin (tetrafluoroethylene) machined from solid wood. The pin fixing structure formed by round cutting does not wobble and is heavyoutput tubewill be held securely. This suppresses poor contact and sound quality deterioration due to slight vibrations during operation, supporting the stable operating environment required of direct-heated triode amplifiers.
Fluororesin has extremely high electrical insulation properties and a low dielectric constant, suppressing leakage and noise even in the output stage where high voltage is applied. It also has excellent heat resistance and maintains reliability even after long periods of use.
Stable electrical contact with phosphor bronze pins and gold plating
The socket pin uses phosphor bronze, which has excellent strength and spring properties. Stable contact pressure can be maintained even after repeated insertion and removal of the vacuum tube, ensuring highly reliable contact even during long-term use.
Furthermore, by applying thick gold plating on the non-magnetic base material, oxidation is prevented and changes in contact resistance are suppressed. By eliminating the influence of magnetic materials as much as possible, the structure is designed to bring out the tones of the 300B and 2A3.
Reliability-oriented parts for building direct-heated triode amplifiers
The UX-4P tube socket is designed with emphasis on material selection and processing precision to achieve both the sound quality and reliability required of direct-heated triode amplifiers. It is a core part that can be used with confidence when manufacturing 300B and 2A3 amplifiers.
