Stam Audio SA-47


The SA-47 is an exact replica of the most revered vocal tube microphone in history, the Neumann U47. With the aid of a Telefunken-Siemens EF800 NOS tube, Dany Bouchard’s D7 capsule and a AMI BV08 output transformer we have managed to gives this replica the true character of an original Neumann U47 at a fraction of the price making it affordable to everyone.


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 D7. Unlike other similar offerings that feature M7 capsule replicas these are 100% hand made by Dany Bouchard in Canada and are professionally skinned with DuPont Mylar.

The SA-47 features premium capacitors on the audio path as well as polystyrene capacitors, which are more stable and much more linear in the top end This makes them the perfect choice for feedback circuitry. Additionally, the unit features a NOS Telefunken tube reducing noise and the output impedance to give this microphone the true character of an original U47 microphone.


We have remained 100% faithful to the original vintage circuit and schematic and have made no compromise in parts which ensures you are get the best possible sounding microphone.


Stam Audio Engineering products are about sound quality first and foremost. Every component of every single unit is premium quality and carefully selected to ensure our units match or even surpass the quality of high end boutique-gear.

So when you see the price for the SA-47 your first thought will probably be: “how is this possible?”

We have made the bold decision to bypass distributors and retailers and use the typical 30% margin on quality components. Whilst we inherit a slightly smaller reach without distribution, we conversely can afford to have a large budget for parts, allowing us to build a better product at a better price than any alternative offerings across all of our product range. Better components mean better recordings.


If you’ve used an original vintage u47 before, we’re extremely confident the SA-47 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 a piece of gear is for you, is to put it through its paces.That’s why the SA-47 comes with a 30-day money back guarantee.
