The SA-251 is an exact replica of the Telefunken ELA M 251 microphone

A 251 replica has been a long-time wish, but it wasn’t until now that we have found the key components that recreate all the sonic characteristics of this classic.

With Haufe in Germany bringing back the original transformers made in the very same machine used 50 years ago and by designing a custom head basket with a dual mesh layer to tame the high frequencies, we have found the final pieces of the puzzle to achieve audio perfection.

The Stam Audio SA-251 is the world’s finest replica of the original Telefunken ELA M 251 multi-pattern tube condenser microphone. This is the only replica available with the original GE-6072A 5 star tube, Haufe T14/1 transformer, and the Tim Campbell’s CK12 capsule, considered by most engineers as the finest brass capsule reproduction built today. By selecting these components and strictly following the original schematic, not only have we have managed to give this replica the true character of an original ELA M 251, but are also the only company to have gone the extra mile to source the original components found in this magical microphone.


The SA-251 is built with premium components

Since the capsule is the single most important component on a microphone’s tone, we have decided to take extra care and use the best replica available, the famous handmade CT12 all brass capsule. Unlike other similar offerings that feature Chinese made replicas, these are 100% hand made in Denmark by Tim Campbell. The SA-251 features premium capacitors on the audio path, a NOS 6072a or 12AT7 Mullard tube (optional GE 6072A 5 start available per request) reducing the noise floor and the output impedance to give this microphone the highest functionality and quality in the market.

Perhaps the most critical component after the capsule is the Haufe T14/1 transformer. This is the original factory made from original blueprints and specs in the very same machine that manufacture them over 50 years ago.

Finally, we have the dual mesh layer: The SA-251 employs a custom made head basket that not only matches the original dimensions but also includes the thin inner mesh layer with a vital influence on the sound of this microphone as it smooths out the top end and acts like a pop filter.


100% satisfaction guarantee – if you don’t love your SA-251, we’ll refund you

If you’ve used the original before, we’re extremely confident the SA-251 will put a big smile on your face every time you use it.

However if you’ve never touched the original before, as gear lovers ourselves we understand that the only way to really know if this microphone is right for you, is to put it through it’s paces.

    Wow, Just WOW! Josh and the team knocked this one out of the park! The SA-251 sounds just phenomenal! I ran it through my 1073 into my Serpent 1176 for a vocal session and the vocals sounded so lush!! It’s the perfect companion for my SA-800 and I can’t recommend this mic enough! (Mine came with the GE 6072A NOS tube)

  2. Martin John Butler

    From the post online, done with only very basic equipment, I’m very impressed. I immediately recognized the true 251 character. I’d love to have one of these to compliment my Stam SA67. I’ve actually used a vintage 251 and it’s unforgettable. I got the same feeling from the SA251.

    Josh and his incredible team have produce an unbelievable modern day replica in the SA-251. It has that je ne sais quoi! the moment you say Mic Check!! I have not been able to take my SA-251 off my microphone stand since it arrived. I am running it thru my GML 2020 mic pre and all I can say is Game Over!!! It does not get any better than this IMO. Stam Audio is a very special company and Josh is a very gifted and talented innovator.

    Depth, glowing presence, and vital clarity. The SA-251 brings back classic sound innovation within the reach of affordability. I once thought home recording would be too expensive for my quality standards, but Stam Audio has made it possible again. A worthy replica of one of the best and most versatile tube microphones ever made. So far it has transformed my vocal and acoustic guitar recordings for the better, and I’m looking forward to recording other instruments.

    I can finally say that high end microphones DO make a difference. Having already bought the SA-87 (which is amazing but a tad dark for some sources)) I was beyond curious to try out the SA-251. When it arrived I powered it up and ran some quick vocal/acoustic guitar tests. JUST AMAZING! This mic gives you that instant polished “mixed” sound with zero effort. SO balanced, SO detailed, and super lush/smooth. Paired with my Daking Mic Pre One I’m finally getting top notch sounds from both my Stam mics. I’m completely floored by the SA-251….Josh, THANK YOU MAN!

    I have worked in some of the best studios in the world and used some of the best microphones in the world. This SA 251 surely holds it own in the quality mic space. It’s a fantastic mic. Very smooth on the top end and the low end doesn’t cover anything up. I recently recorded vocals on an artist and I used a vintage C12. I have to say that is an experience. It wouldn’t be fair to compare a $20k mic to the SA 251 but I would have to dare most ears to tell the difference between the two after proper eq and compression applied in a final mix. Of the microphones I have the SA 251 is right up there with the best. To me by far the best bang for the buck out there. Josh and the Stam team are very accessible and helpful. Shout out to Macarena for staying on top of things with excellent customer service.
