If you loved the Stam SA-670 Mk1 Stamchild you will love The Stam SA-670 Mk2 Stamchild even more. Our take on the most iconic and finest sounding tube compressor in history, the Fairchild 670.

Recreating the finest sounding stereo tube compressor in history
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 secondly the compression curve had to be identical to the original. With this in mind we developed a few upgrades and carefully tested each component and its interaction with the circuit.

After many months of research and test we determined there was a way, and so the Stam SA-670 Mk2 Stamchild was born.

With the aid of 8 premium transformer reproductions made by AMI in the US and Brian Sowter in the UK and the use of 18 Tubes we have managed to make this unit virtually indistinguishable to the original.

The Stam SA-670 Mk2 Stamchild also uses a German made chassis and faceplate, as well as the historically correct VU meter, Knobs, and Neutrik XLR connectors.

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 on the sound.

We also changed the control amp to a hybrid setup, while maintaining the Tube character, Control Amp Input Transformers and 2 extra Tubes to not only match the amplifier but also the compression curves and add DC Threshold Control.

With these measures we are able to bring the cost down while preserving the original tone, without touching the audio path, and without removing the character produced by the transformers and tube on the control amp.
