-4-Stage amplifier circuit.
Circuit configuration comes from the first-stage, phase reversal, drive stage, output stage employs 4-stage amplifier configuration. In the first stage
Used for low noise and high-gain 12AX7, next steps in 12 AU 7 directly to the phase inverting circuit. Deliver 5881 12AU7 drive-a reputation for low frequency high amplification rates in adopted in カソードフォロワー, in the output stage with the reputation as the audio output tube to UL connections in high driving power.
-Masonry lap of high-efficiency power supply transformer
Piling wrap low magnetic leakage, high efficiency along with the power transformer the adoption, to enable sufficient energy supply to the wide dynamic range signal fine voice also plays beautifully.
-Integrated box construction chassis with 10 mm thick aluminum panels
Design polished piano paint exterior and up to 10 mm thick aluminum panel brushed through heavy feeling. Heck adopted box construction chassis chassis that supports them. High strength provides no sense of noise by eliminating due to the screw connections of the increase the stability of the chassis potential stable music playback.
Solid machined aluminum with diameter 40 mm plano-convex lens-like original design, adopt the insulator. Achieve reliable mechanical ground.
-Gold-plated input/output terminals
Adopt a high reliability, superior junction stability to the input terminals and speaker terminals and GND terminals gold-plated terminals. Provide high quality stable over a long period.
