  • Leak's "RC/PA/U" Pre-Amplifier: A High-Fidelity Solution

    Leak introduced the "RC/PA/U" pre-amplifier in November 1950, building upon their earlier "RC/PA" model. This new version offered user-selectable equalization for both 78 rpm records and the new LP micro-groove format, catering to the evolving recording industry.
    The unit cost £8-15s, reflecting its advanced features.

    Technical Highlights:

    • Miniature twin triode valve with negative feedback for minimal distortion.
    • User-selectable tone controls with minimal distortion due to negative feedback design.
    • Step-position switches for precise control over bass and treble, ensuring accurate level response.
    • Design prioritized fidelity, avoiding excessive bass or treble boost that could introduce distortion.

    Targeted Audience:
    The RC/PA/U targeted audiophiles and professionals seeking high-fidelity reproduction. The step-position switches and design choices reflected a focus on accurate control and sonic purity, aligning with studio-grade equipment.

    Leak emphasized that proper usage was crucial for optimal results. Abusing the tone controls wouldn't compensate for deficiencies in other components like loudspeakers. The maximum bass boost was intended for very low listening volumes, acknowledging the ear's reduced sensitivity to bass at such levels.

    The RC/PA/U showcased Leak's commitment to innovation and precision in the evolving world of high-fidelity audio.
