L2 - Specifications

L2 TECHNICAL FEATURES

Circuit Design is Pure Class-A, Single-Ended Triode, Zero Feedback, Dual-Mono.
Audio Circuit has no Cathode Followers or Buffers.
To prevent unwanted AC-induced distortions, the L2 features an External Power Supply housing three separate supplies and a large-shielded, custom-wound transformer.
In the main chassis, four-separate, fully-regulated FET power supplies drive the audio circuitry in addition to separate filament supplies.
Automatic-timed muting with Tri-Color LED indicator.
Low-light Illumination for Selector Switch and Master Volume Control Knobs.
Standby Mode avoids cold starts and prolongs tube life and circuit components.
Active Tape Output and External S/S Output Buffers are FET regulated, set for unity-gain.
All circuit boards are hand-soldered using the finest silver solder available. All polypropylene and polystyrene film capacitors used are proprietary designs of Audible Illusions. Resistors are precision 1% Holco and Roederstein.
Proprietary gold-plated RCA Jacks with Teflon insulators.
Master stereo volume is laser-trimmed Alps. Balance Controls are Precision Stepped Attenuators.
Handcrafted in the USA.
