Vintage u87 Microphone


The SA-87 is an exact reproduction of a 1979 (rev16) vintage Neumann u87 microphone considered by most engineers as the finest sounding u87 ever made. We have recreated the distinctive character of this microphone to the very last drop and for the first time at a price that makes it affordable to anyone.


Since the capsule represents 90% of the microphone’s tone we have decided to make an extra effort and use the best one available. The Heiserman Audio HK- 87 capsule is based on a 1960's vintage set of original back plates which offers a much more vintage tone than current offerings, it uses brass rings to hold down the Mylar and nylon screws to isolate the capsule halves. Unlike other similar offerings that feature Chinese made capsules all of these are 100% hand made by Eric Heiserman in the USA and are professionally skinned with DuPont Mylar in Chicago.

The SA-87 features premium Vishay capacitors on the audio path as well as polystyrene capacitors, which are more stable and much more linear in the top end making them the perfect choice for feedback circuitry and a Sowter 1303f output transformer.

Optional Sowter 1303f transformer is also available.


The main difference with current offerings is polarization voltage, while current models future 60V the vintage units were rated at 48V, the lower voltage of polarization makes the capsule sound more musical and mellow as well as increasing the microphone’s headroom making it less susceptible to distortion.

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 sounding microphone possible.


Stam Audio Engineering products are about sound quality first and foremost. Every component of every 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-87 the first thing you probably think is: how is that possible?

We have made the brave decision to bypass distributors and retailers and use that 30% margin on components. While we are able to reach less people without distribution we can afford to have a large budget for parts allowing us to build a better product at a better price than any other offerings in all of our product range. Better components mean better recordings.

That said, how much will a SA-87 set you back?
