Following the announcement of several new hardware units and a microphone last month, Stam Audio has just revealed the StamChild 670 MK2. The unit is Stam Audio's second and improved take on the iconic Fairchild 670 with more transformers, more tubes and now an identical compression curve as the original. Here's the details from the press release...

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, Stam Audio have managed to make this unit virtually indistinguishable to the original.

The StamChild SA-670 MK2 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 Stam Audio have made some modern implementations which do not affect the audio path. They have changed the tube-based power supply to a solid state one, which has no bearing on the sound.

The control amp has also been changed 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, Stam Audio 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.
