  • 25-Watt Hybrid, HY50

    A brand new hybrid fabrication technique, recently perfected in our laboratories, has enabled us to achieve our latest range of completely integrated devices.
    We have now finally reduced the modular amplifier to a simple input/output device requiring only the addition of a basic unstabilized (split-line) power supply.
    The HY50 takes medium power modules to their logical conclusion by incorporating with it a heatsink, which is designed in special high conductivity alloy, sufficient for normal audio use without additional chassis sinking. All this without significantly increasing the size of the module comparable in size to a packet of 'King-size' cigarettes. Consistent with modern thinking a triple-rated output circuit with a load fuse allows for peak transient response without distortion but ensures the necessary protection.

    Electrical characteristics:

    Output power: 25W RMS into 8 Ω.
    Load Impedance: 4 - 16 Ω.
    Input Sensitivity: 0 dB (0.775 V RMS)
    Input Impedance:  47 kΩ.
    THD: Less than 0.1% at 25 Watts, Typically 0.06% 
    S/N Ratio Better than 75 dB
    Freq. Response: 10 Hz - 50 kHz, ±1 dB
