L-3000 Line Stage Pre-Amplifier

A line stage that has earned its reputation amongst some of the world's finest. Kang Su Park's more costly transformer coupled output design featuring Permalloy Nickel Cores, NOS Mullard E810F gain tubes, ultra-low noise Patented Gel Tube sockets, custom Allnic built 41 Silver Stepped motorized and remote attenuator all housed in an aluminium chassis that is substantial in its engineering and build quality.

Available upon special request with Home Theatre Bypass and for those with ultra sensitive speakers output transformers easily wire-able at 14 or 20 dB gain.

 

The L-3000 has the following features:

  • Single gain stage – A single gain stage circuit uses only one tube for amplification (“gain”). This reproduces a purer, more detailed, more spacious and more dynamic sound than multi gain stages.
  • Line output transformer coupling Allnic Audio manufactures its own transformers and uses what it views to be the best core material, Permalloy. Allnic Audio's unprecedented, wide (16Hz ‐ 75kHz, ‐3db), low distortional, and ultra‐flexible (up to 50kHz square wave response) output transformer helps Allnic Audio to realize the ideal transformer coupled preamplifier. Gain tubes are also carefully selected for three critical factors for function with the Permalloy core output transformers: high gm, low internal resistance and high mu.
  • Constant and low output impedance – One of the benefits of transformer coupling is that it facilitates constant low output impedance. Low output impedance is critical to the design of a good preamplifier. The L-3000 has a150 ohm (150Ω) constant output impedance at all frequencies.
  • Advanced tube technology voltage regulation ‐ For quieter and more dynamic operation, the L‐3000 has an ultra-high speed automatic voltage regulation circuit, utilizing vacuum tubes. This also protects the amplifying tubes from change in the AC line supply and copes with any abrupt, internal current demand
  • New vacuum tube damping technology – Allnic Audio’s patented "Absorb GEL tube damper" technology prevents harmful vibrations from reaching the signal / gain tubes and, therefore, prevents micro-phonic noise propagation in the tubes.
  • Precision attenuator volume control – The L3000 does not employ a digital IC volume control or a low cost carbon film volume control with a motor. Allnic Audio has developed a precision oil clutched motorized attenuator; the L-3000 has no (± 0db) channel unbalance at any volume level.
