Alchemy Series Microphones


The ideal choice for discerning engineers, musicians, and producers.

Designed, hand-built, and tested to strict quality standards in Connecticut, USA, the Alchemy Series is TELEFUNKEN Elektroakustik’s next generation of large diaphragm tube condensers. These new microphone models feature unique sonic profiles developed from the ground up. The bold new voicings of the Alchemy Series are the TF29, TF39, TF47, and TF51.

  • TF29 Copperhead
    The fixed-cardioid TF29 is a workhorse microphone, accurately capturing nearly any source put in front of it with a natural tonality.
  • TF39 Copperhead Deluxe
    The TF39 expands on the "Copperhead" sound by adding 3-pattern selection between cardioid, omnidirectional, and figure-8.
  • TF47
    With a deep low end and a forward midrange, the TF47 delivers a warm and punchy sound reminiscent of the U47 and M49.
  • TF51
    The large diaphragm multi-pattern TF51 exhibits a smooth midrange and airy top end similar to the ELA M 251E and C12.


Future classics, not clones.
With the combination of vintage microphone elements and modern fidelity and reliability, the Alchemy Series delivers microphones each with a distinctively original sonic fingerprint. The Alchemy Series is an evolution and refinement to past models in the R-F-T Series (CU-29 Copperhead, AR-51, and AK-47 MkII), benefitting from over a decade of in-house microphone design and production.

Professional designs, superior functionality.
TELEFUNKEN Elektroakustik has implemented numerous improvements sonically and mechanically to the Alchemy Series, tailored all the way down to the accessories. Boasting newly designed custom head grilles for transparency and openness, hand-plugged circuit boards, and selected American and European vacuum tubes and transformers, no detail was left unaddressed. All systems ship in a sleek, compact, protective case for easy transport and storage. Included are two modern mount options, microphone dust cover, high-flex 7-meter cable, and an American-assembled power supply.

Real trusted quality, built to last.
Like all TELEFUNKEN microphones, the Alchemy Series is assembled in the same American facility as the legendary Diamond Series (ELA M 251E, C12, and U47) by a small, dedicated team of engineers and technicians. Each microphone is individually tested and listened to. All critical components are quality controlled in-house before assembly, including capsule frequency sweeps, vacuum tube burn-in, and noise grading. These high standards lead to extremely tight tolerances from microphone to microphone - something few in the industry can claim.

The ideal choice for discerning engineers, musicians, and producers.
The Alchemy Series combines timeless sound quality with TELEFUNKEN reliability in an affordable package. Whether it’s the home studio or a commercial facility, the Alchemy Series is suited for any recording environment.
