INTRODUCING THEL-3000PREAMPLIFIER
TheL-3000is Allnic Audio’s best line stage preamplifier. Like all Allnic Audio products, it uses Permalloy (Iron and nickel alloy) for its transformer cores. Allnic is grateful to Mr. G.W. Elmen of Western Electric for inventing Permalloy for transformer core use, and in so doing, providing an enormous service to recorded music listeners everywhere.
TheL-3000has 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–TheL-3000is “transformer coupled”. In tube amp circuitry, there are two coupling methods; one is capacitor coupling and the other is transformer coupling. Capacitor coupling is the traditional, low cost method. It is somewhat stable but transfers only voltage, not wattage (i.e., not real energy). With transformer coupling, about 90% of real wattage is transferred (there is still a transformer loss of about10% of wattage–voltage is not affected).
Transformer coupling is superior to capacitor coupling. However, all the advantages of transformer coupling depend on the quality of the transformer and on the choice of tubes. 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 ultraflexible (up to 50kHz square wave response) output transformer helps Allnic Audio to realize the ideal transformer coupled preamplifier. Of course, gain tubes are also carefully selected for three critical factors for function with the Permalloy 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. TheL-3000has a 150ohm (150Ω)
constant output impedance at all frequencies. In capacitor coupling (C-R coupling), a “cathode follower circuit" is usually used to lower output impedance. Unfortunately, this method of lowering output impedance is accompanied by high distortion andhas an "L" shaped output impedance curve.Please compare the two graphs below, especially for low frequency response.
 No negative feedback design
 Advanced tube technology voltage regulation-For quieter and more dynamic operation, theL-3000has 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 withany abrupt, internal current demand.
 New vacuum tube damping technology–Allnic Audio’spatented "Absorb GEL tube damper" technology prevents harmful vibrations from reaching the signal / gain tubes and, therefore, prevents microphonic noise propagation in the tubes. The Allnic Audio Absorb Gel damper technology effectively solves a problem that plagues most tube amplification systems. Provided other tube components do not introduce microphonic noise into your system, with the Absorb Gel damping system, you will enjoy a degree of transparent sound that will surprise and please you.
 Precisionattenuator volume control–TheL-3000 does not employ a digital IC volume control or a lowcost carbon film volume control with a motor. Allnic Audio has developed a precision oil clutched motorized attenuator; theL-3000has no (± 0db) channel unbalanceat any volume level.
 Pure Class A operation
 Pure balanced operation
 As are all Allnic Audio products, theL-3000is fully RoHS (EU Reduction of Hazardous Substances regulation) compliant in construction and materials
