TELEFUNKEN Elektroakustik is pleased to announce the final production run of its current Alchemy Series Stereo Sets, featuring the TF29 Copperhead, TF39 Copperhead Deluxe, TF47, and TF51 large-diaphragm tube microphones.
Please note that this production run represents the last opportunity to purchase these Stereo Sets in their current configuration, including the FC03S hard-shell locking flight case and M901S dual tube microphone power supply. Once this production run is complete, these specific accessories will no longer be manufactured.
A New Generation of Alchemy Stereo Sets
The Alchemy Series Stereo Sets will be re-introduced at NAMM 2027 in an updated configuration. The new Stereo Sets will feature a new ZC03S soft-shell zipper case and a lower-profile M903S dual tube microphone power supply.
This transition represents the next evolution of the Alchemy Series Stereo Sets, while preserving the performance, matching, and value that have made the TF29 Copperhead, TF39 Copperhead Deluxe, TF47, and TF51 popular choices for professional recording applications.
Current Production Alchemy Series Stereo Sets
The Alchemy Stereo Sets come with two frequency and gain matched microphones, plus a premium dual power supply, two M 803 Cables, two M 703 shock mounts, two M 782 stand mounts and a hard shell FC03S locking combination suitcase. The M 901S power supply features two 9-position variable polar pattern switches providing each mic six additional settings beyond the cardioid, hyper-cardioid and omni-directional patterns.
TELEFUNKEN power supplies feature the traditional styling of vintage Austrian models, partnered with the improvements of modern component technology and circuit board design. These modern features include a slow-ramping filament voltage to extend tube life and full regulation to ensure the microphone will always operate the same, regardless of line voltage variations or location. Full regulation also means that stereo power supplies can also safely power only one microphone at a time at correct operating voltages, if needed.
TELEFUNKEN power supplies are hand-built in South Windsor, CT, USA with premium components including signal transformers, Nichicon capacitors, Neutrik connectors, double-thick circuit boards for structural integrity, and a PCB layout made to maximize current handling. They are built well over-spec to ensure reliability and safe operation for decades. Each power supply is calibrated to the specific microphone system it comes with and is burned in as a full unit to ensure optimum performance and operation. Variable pattern power supplies feature nine polar patterns from Omnidirectional to Figure 8. The polarizing component network is identical to that of the original AKG C12 power supplies, providing the optimal impedance and voltage to the capsule.
TELEFUNKEN microphone flight cases are specially designed to protect the delicate capsules, vacuum tubes and electronic components. A unique blend of hardwoods is utilized in the construction of the shell, while the outside of the case is wrapped in 1000pt Cordura, the world’s finest traveling fiber. Dual combination locks and trim in nickel create an understated, classic look. An embroidered serial number (when applicable) complete the package. The suitcase holds two microphones (46mm diameter by 200mm length), one stereo power supply, two tube microphone cables and two shock mounts.
