On one unit, One of the meters led flickers i tiny bit. ( nothing effect by the signals ) 
The attack knob is not stepped. 

The M97 is a modern take on an idea that has been evolving for 70 years — a triode amplifier with a variable amplification factor (expressed mathematically as ‘µ’ or ‘mu’), configured to provide dynamic range compression and limiting for high-quality audio.

This project took several years to complete, and involved a huge amount of brainstorming, experimentation, and trial and error, even before the first prototype was built.  Many more hours were spent rethinking, redesigning, rebuilding, and refining.  The process was grueling yet fascinating, exhausting yet exhilarating. (!!)  Best of all, it resulted in what we believe is an outstanding modern variable-mu1 compressor with an excellent set of features and an amazing sound.

The Design Notes below shed some light on the philosophy behind the design, while also pointing out some of the limitations found in traditional vari-mu compressors, and the solutions Electronaut devised in order to achieve a tangible improvement.

Design Notes

The century-old triode vacuum tube continues to set an amazing standard of sound quality, demonstrating its persistent relevance decades after being eclipsed by cheaper alternatives. The variable-mu compression amplifier, as a single-stage, transformer-coupled triode amplifier controlled by a powerful DC amplifier, survives as a gold standard compression tool for the recording studio.

For reasons explained below, Electronaut set out to design a new variable-mu compressor with no regard for the specific character of other historical variable-mu compressors. Interest in the potential of the technique, coupled with the availability of superior components and manufacturing capabilities, demanded an attempt at producing a compressor whose capabilities were as good or better than the state of the art, and whose features provided improved usability and a more enjoyable experience.

Extraordinary variable-mu compressors already exist, so any new design needs to clear a high bar. No obvious limitations can be allowed, and no inconveniences can be tolerated. This is not a trivial task, and upon investigation it became clear that there were many problems that would need to be addressed. A small collection of some of those problems and the solutions Electronaut worked out appears below, because their descriptions do a pretty good job conveying the merits of the M97 compressor.
