Telefunken Elektroakustic TF51 Large Diaphragm Tube Condenser Microphone #0991 (Used)

The Telefunken TF51 Tube Condenser Microphone is a fresh take on the “Austrian” microphone sound associated with the legendary Telefunken ELA M 251E and C12. The TF51 continues this legacy, exhibiting a smooth midrange and airy top end and capturing every nuance in pleasant detail. The TF51 is a reliable first choice for stand out vocals, acoustic instruments, and percussion. Similar to the 251E and C12, the TF51 features a CK12-style edge terminated capsule, 6072A vacuum tube, and custom-made Haufe transformer. The combination of these components provides a beautifully open and smooth sonic profile, with a certain level of articulation that can only be described as lifelike.
