Telefunken ELA M 251F Tube Condenser Microphone

Multi-Pattern Tube Condenser Microphone

The ElaM 251 F is a large-diaphragm tube condenser mic, presented as a low-cost version of Telefunken Elektroakustik’s historically-accurate ElaM 251E reproduction.

The primary differences between the ‘E’ and ‘F’ versions are:

• The 251F has an imported, “modern” power supply, rather than the historically-accurate “lunchbox”-style 251E power supply.
• The 251F uses the company’s TK-12 capsule, rather than their CK-12 capsule.
• The 251F’s “no frills” packaging does not include the the vintage-style locking flight case of the 251E.

The 251F’s amplifier circuit is identical to the company’s 251E reissue; the tube is a JAN 6072A, and the transformer is custom-wound by Haufe. The original Telefunken 250/251 modular construction technique is retained.
