 L-3000A Line Preamplifier

PRINCIPAL FEATURES

⊙ Single gain stage

    Single gain stage circuit uses only 'one' tube in amplification, which reproduces
   purer, more detailed, more spacious and more dynamic sound than multi gain stages,

    just like through one window glass we can see outside scene more clearly than
    through several window panes.

⊙ Line output transformer coupling of large pure Nickel Alloy core.

    In tube amp circuitry, there are two coupling methods, one, capacitor coupling
    the other transformer one.
    The former, traditional, low cost and somewhat stable transfers only voltage not
    wattage (not real energy), the latter conveys about 90%(transformer loss about10%)
    of real wattage.
    No comparison between them for the driving capacity of power amplifier.
    All the advantages of transformer coupling too simply depend on the quality of
    transformer and on the choice of tubes.
    Allnic's unprecedented wide (16Hz ~ 75kHz, -3db), low distortional and ultra
    -flexible (up to 50kHz square wave response) output transformer realizes this
    ideal preamplifier. We also choose the right tube (ideal three factors, high gm, 
    low internal resistance and high mu) for this position.
 
⊙ Constant and low output impedance

    Low output impedance is prerequisite to a good preamplifier.
    L-3000A has 150Ω constant output impedance at all frequencies. In C-R coupling
    "the cathod follower circuit" usually being applied to lower output impedance
    accompanies high distortion problem and has "L" shaped output impedance curve.  
    Please compare two graphs below especially for low frequency response.




  
⊙ Advanced Voltage Regulation technology by tube

    For quieter and dynamic operation L-3000A has ultra high speed automatic voltage
    regulation circuit, made by pure vacuum tubes for each channel.
    This also protects the amplifying tubes from any change of AC Line and copes with 
    any abrupt internal current demand.

⊙ Automatic muting system

    About 40 seconds muting circuit prevents any harmful transient to power amplifier
    and to loud speakers, while warming up the preamplifier.

⊙ Convenient analog current meters

    Two illuminated front panel meters show all the status of L-3000A's operation,
    any failure or any damage in parts will make the needle off the dot.

⊙ New vacuum tube damping technology

    Our patented "Absorb GEL tube damper" technology prevents any harmful
    vibration or microphonic noise so far so untreatable fundamentally.
    With our damping system you can enjoy real clean and pure sound.

⊙ Remote controller with precision attenuator volume control

    No digital IC volume control or cheap carbon film volume with motor.
    We developed a precision oil clutched motorized attenuator, L-3000A has
    actually no(± 0db) channel unbalance at all levels of volume control.

Me Kang su Park does not rest on his laurels. He has built an upgraded L3000 (formerly L4000) This unit possesses the new output transformers. The end result is a more refined presentation with masculinity. Wider bandwidth resulting a larger sound stage, smoother top end, greater sense of dynamic ease with increased low low level resolution. This easy to instal upgrade is available if you already possess L4000 or L3000.

THIS LINESTAGE RIVALS ANY AND ALL FOR VALUE, PERFORMANCE AND BUILD QUALITY.

See you local dealer or call Hammmertone Audio. THE OPTIONAL UPGRADE IS AVAILABLE NOW.
