Notes: Clones Neve 1073/1272 (BA183) circuit. Carnhill input/output transformers (Marinair/St. Ives lineage). FLAG: this is the genuine API 500-series-compatible module (fits standard 500-series lunchboxes/racks) and explicitly will NOT work in SCA's own CH02/PC01 chassis -- distinct from the SCA-proprietary-format 'N72' classic-series module. Available as DIY kit or assembled.
