Telefunken TF51

A modern classic
The Telefunken TF51 is a fantastic high-end tube microphone designed as a combination of the legendary C12 and Ela M251E microphones. The result is a microphone that gives a soft delicious midrange and air at the top. Telefunken is well known for the re-creation of the legendary microphones found in the company's Diamond series and the design philosophy is fully part of the more affordable TF series of microphones to which the TF51 belongs. The AR-51 uses the same German-built Haufe T14 / 1 output transformer as the C12 and Ela M251, combined with a NOS ECC81 tube and a TK51D capsule. The TF51 comes complete with suspension, M901 power supply, tube-microphone cable and carrying case for the microphone.
