StamChild SA-670

Vacuum Tube Compressor

The StamChild SA-670 is our take on the most iconic and finest sounding tube compressor in history, the Fairchild 670.

While developing this project we had two main objectives, first and foremost the audio path had to remain as close as possible to the original units and it had to be affordable. With this in mind we developed a few prototypes and carefully tested each component and it’s interaction with the circuit, after many months of research and test we determined there was a way and so the StamChild SA-670 was born.

With the aid of premium transformer reproductions made by Brian Sowter in the UK and the use of four JJ 6386 and two 12AX7 tubes we have managed to make this unit virtually indistinguishable to the original. The SA-670 also uses premium Vishay capacitors, Ohmite carbon resistors, a German made chassis and faceplate as well as the historically correct VU meter, Knobs and Neutrik XLR connectors.

In order to reduce the cost of manufacturing these units we have made some modern implementations which do not affect the audio path. We have changed the tube based power supply to a solid state one which has no bearing in the sound as well as changing the control amp to a hybrid setup maintaining the tube saturation.

With this measure we were able to greatly reduce the cost of production while preserving the original tone without touching the audio path and without removing the saturation produced by the tube on the control amp.

100% SATISFACTION GUARANTEE

If you’ve used an original before, we’re extremely confident the SA-670 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-670 comes with a 30 day money back guarantee. This allows you to get it into your rack and see how it impacts your recordings. If you love it (and we think you will!), great… keep the unit and create amazing music with it. If not, no problems. Just send it back to us and we’ll fully refund your purchase. Don’t worry, whichever way you decide to go we will remain friends.

ZERO COMPROMISE. SURPRISINGLY AFFORDABLE.

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-670 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

That said, how much will a SA-670 set you back?

The stock price for the SA-670 is $2,999US.

Right now though, if you put a $500 deposit down to pre-order your unit you will get the discounted price of $2,699.00. The remaining of the balance will be $2.199 USD
