The U17 is known for its unique hybrid circuit design that combines vintage and early solid-state technologies: While the original hardware had very few controls,

Employs six DS62 germanium crystal diodes for floating gain reduction.

The original hardware was custom-built by in Hamburg for the post-war NWDR (Northwest German Broadcasting) network. Only a few dozen units were ever produced, primarily used to boost signal-to-noise ratios in AM radio transmissions. It is famously documented in the "Braunbuch" , an anthology of technical descriptions for German broadcasting hardware. Technical Architecture The is a high-end audio compressor plugin that
