Pioneer TX-900 Solid-State AM/FM Stereo Tuner — Made in Japan — Rosewood Trim

The Pioneer TX-900 is a rare and beautifully crafted professional-grade AM/FM stereo tuner from 1970–71, representing Pioneer’s top-of-the-line tuner offering at the dawn of the high-fidelity era — a stunning piece of Japanese audio engineering finished in brushed chrome and genuine Brazilian rosewood trim.

Designed without compromise, the TX-900 was built for audiophiles who demanded maximum sensitivity and reception precision. Its front end employs three field-effect transistors (FETs) across two RF amplifier stages — an advanced topology for its time that delivers exceptional signal-to-noise performance and stable reception even in weak-signal environments. The IF section features a pair of crystal filters, providing the remarkable selectivity and capture ratio that distinguishes this tuner from lesser designs of the era. Two dedicated tuning meters — one for signal strength, one for stereo tuning centre — make precise station alignment a satisfying and intuitive experience.

The analogue tuning scale offers smooth, linear dial movement with a weighted feel, and the front panel is logically laid out with a rotary selector switch for FM Auto, FM, and AM modes, a variable muting level control, an MPX Noise Filter switch, and separate output level controls for FM and AM — a level of control rarely found in consumer tuners of any era. A switched AC outlet on the rear panel adds practical convenience for associated equipment.

Aesthetically, the TX-900 is simply outstanding. The brushed chrome faceplate is complemented by genuine Brazilian rosewood side panels and trim accents — a combination that looks as sophisticated today as it did over fifty years ago, and that integrates beautifully with vintage wood-cabinet systems or as a statement piece on a modern shelf.

This unit has been tested and inspected by our team at Radique Audio and is ready to perform.
