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 250 E	CK-12	6072a	Cardioid, Omni	Historical	$10,495
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.
