Telefunken Elektroakustik Ela M 251 F
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.
Telefunken Elektroakustik manufactures numerous variations of the ElaM 250/251 family of microphones:
Model | Capsule | Tube | Patterns | PSU | MSRP (2010) |
Ela M 250 | CK-12 | AC-701 | Cardioid, Omni | Historical | $13,495 |
Ela M 251 | CK-12 | AC-701 | Cardioid, Omni, Figure-8 | Historical | $13,995 |

Ela M 251 E | CK-12 | 6072a | Cardioid, Omni, Figure-8 | Historical | $10,995 |
Ela M 250 F | TK-12 | 6072a | Cardioid, Omni | Modern | n/a |
Ela M 251 F | TK-12 | 6072a | Cardioid, Omni, Figure-8 | Modern | ($5,995) |
Ela M 251 T | CK-13 | 6072a | Cardioid, Omni, Figure-8 | Historical | n/a |
(MSRP current as of Nov, 2010)
Note the similarity between the ElaM 250F and ElaM 251F — the sole difference is that the 251F has a third polar pattern: figure-of-8.
The ElaM 251F “no frills” package included the 251F microphone, an imported power supply, a swivel mount, a hardwood storage box for the mic, and a power cable.
