Vacuum tube audio preamplifiers have recently found renewed interest. This study recalls the main requirements that this type of equipment must meet, and analyzes an example. The experimental approach followed to measure performances is described. These performances are exposed, and the associated uncertainties are determined. The reviewed example meets the advertised specifications.
