Includes the complete wiring harness, connectors, and separate tube amplifier output stage. Fitment: Correct period-style aesthetic often sought after for classic European restoration projects (such as vintage Mercedes-Benz dashboards). Please review all photos and the included video demonstration, which shows the actual power-up sequence, dial illumination, and live tuning response across the bands. Tested, complete, and ready for your restoration project.
