  • The Heathkit AA-30 is a vintage vacuum tube stereo power amplifier originally released as a kit in 1960. It is known for its compact design and high-fidelity performance, delivering 14 watts per channel of power.

    Technical Specifications:
    According to vintage manuals and technical data from rsp-italy.it and eBay listings, the amplifier features:
    Power Output: 14 watts per channel into an 8Ω load.
    Frequency Response: 20 Hz to 20 kHz.
    Speaker Impedance: Compatible with 4Ω, 8Ω, and 16Ω speaker loads.
    Vacuum Tube Complement: Uses a total of nine tubes:
    4 x EL84 (output tubes).
    4 x 7199 (driver/phase inverter tubes).
    1 x GZ34 (rectifier tube).
    Controls: Includes right and left channel gain controls and a phase switch. 

    Design and Performance:
    Experts and hobbyists on platforms like The Vintage Audio Shop highlight the amplifier for its "sweet" sound and impressive soundstage despite its modest power rating. 
    Layout: The unit is noted for a clean, mid-century modern aesthetic and layout.
    Restoration: Common maintenance for these vintage units involves replacing aged can capacitors and paper-in-oil capacitors to ensure they meet original specifications.
    Legacy: It was marketed as a high-fidelity "build it yourself" kit that offered value and performance comparable to higher-priced factory-built equipment of the era.
