No negative feedback design

Advanced tube technology voltage regulation - For quieter and more dynamic operation, the
L-7000 has an ultra-high speed automatic voltage regulation circuit, utilizing vacuum tubes,
including the 300B triode. This also protects the amplifying tubes from change in the AC line
supply and copes with any abrupt, internal current demand.
•
Precision attenuator volume control – The L-7000 does not employ a digital IC volume
control or a low-cost carbon film volume control with a motor. The L-7000 uses the
WORLD'S FIRST 61 step, constant impedance, "bridged" type attenuator, standard on all
units produced after May 2019. Allnic's new attenuator is now the most sophisticated on
the market, and we believe, without a doubt, also the absolute best sounding. With fixed
impedance and no (± 0db) channel imbalance at any volume level, this revolutionary and
currently unique, oil clutched, motorized attenuator will astound users with its elevation of
the fidelity and purity of any system in which it finds a home.
•
Pure Class A operation
•
Pure balanced output stage
•
As are all Allnic Audio products, the L-7000 is fully RoHS (EU Reduction of Hazardous
Substances regulation) compliant in construction and materials
A world's "first of its kind" for Allnic Audio
61 STEP CONSTANT IMPEDANCE BRIDGED TYPE ATTENUATOR
Allnic Audio's newly developed 61 step constant impedance bridged type attenuator, a world's
first, is installed inside the L-7000, which contributes to the L-7000's outstanding dimensional
sound. It does so by ensuring that the attenuator's impedance is absolutely constant across all
frequencies. This is in addition to the zero channel imbalance, a standard feature of Allnic's in-
house produced, motorized attenuators.
