Takatsuki TA-274A Rectifier Tube | 4-Pin UX

Description

Takatsuki TA-274A 4-Pin UX Rectifier Tube

The Takatsuki TA-274A is a premium Japanese rectifier twin-diode tube developed for amplifiers using the classic 4-pin UX socket. Based on the renowned TA-274B, the TA-274A combines Takatsuki’s precision manufacturing, meticulous craftsmanship and strict quality control with a specially developed UX base.

Created for users of compatible vintage and high-end valve amplifiers, including classic Western Electric designs, the Takatsuki TA-274A offers the same uncompromising manufacturing philosophy found in Takatsuki’s reference vacuum tube range.

Takatsuki TA-274A Made in Japan Quality

Takatsuki Electric Industry is one of Japan’s specialist manufacturers of high-end audio vacuum tubes. The company revived Japanese audio vacuum tube production with the TA-300B and later introduced the TA-274B rectifier tube.

The Takatsuki TA-274A was developed from the TA-274B platform but features a newly designed 4-pin UX base, allowing it to be used with amplifiers equipped with the traditional UX socket.

As with the TA-300B and TA-274B, the TA-274A is manufactured with careful attention to parts selection, machining accuracy, vacuum quality and final inspection.

4-Pin UX Base for Classic Amplifiers

A defining feature of the Takatsuki TA-274A is its dedicated 4-pin UX base. This design was created specifically for amplifiers that use the classic UX socket format.

The TA-274A therefore provides an especially attractive option for owners of vintage-style valve amplifiers and systems inspired by classic Western Electric designs.

High Reliability and High Precision

Takatsuki applies the same uncompromising approach to the TA-274A rectifier tube as it does to its other reference tubes. Particular attention is paid to the quality of components, mechanical construction, vacuum processing and production consistency.

Each tube is manufactured and inspected with the goal of achieving stable electrical performance and long-term reliability.
