Introducing JUDE — an official collaboration between Warm Audio and legendary British console builder Sound Techniques.

Warm Audio hasn’t recreated a classic Sound Techniques preamp — it has partnered with Sound Techniques to put the exact original circuit back into production.

Designed by Geoff Frost, Sound Techniques consoles were at the heart of the golden era of British recording, with consoles installed at studios including Trident, De Lane Lea, Sunset Sound and Elektra Sound Recorders.

The A-Range console at Trident Studios helped shape recordings by The Beatles, David Bowie, Elton John, Queen and many more — including Hey Jude, the recording that ultimately gave this preamp its name.

For decades, access to this circuit has largely meant finding original Sound Techniques hardware.

Built directly from the original Sound Techniques console preamp schematics, JUDE preserves the original signal path, including the dual-discrete 3035 Class-A amplifier, Geoff Frost's original Z-Match impedance circuit and custom-spec CineMag transformers.

Not based on it. Not a faithful recreation. The original Sound Techniques circuit, back in production.

JUDE will be available in both single-channel and two-channel stereo versions.
