Product Details
Price includes one independent amplifier for each of the left and right channels (two in total), arranged in a mirrored configuration!
【Product Features】
◆ Fully AC filament lighting is used, delivering a lively and dynamic sound. When paired with speakers of 90dB sensitivity, no AC hum noise is audible, creating a feeling of silence as if the unit is turned off. (When using a 5H choke coil)
◆ Utilizes one 6N8P preamp tube dedicated to audio for two-stage amplification, and one for phase inversion drive. The power tubes can use EL34 or KT88, suitable for driving speakers with an impedance of (4-8) ohms and a sensitivity above 88dB.
◆ Rated output power: 35W x 2 (Due to the strong overload capability of vacuum tubes, the actual undistorted output power is comparable to a 120W+120W transistor amplifier! Since all stages operate in Class A amplification, distortion is low, delivering sweet, smooth, and highly enjoyable sound quality!)
◆ Precision metal film resistors with 1% tolerance and imported electrolytic capacitors are used. Power supply filtering employs Philips main capacitors and Japanese brand auxiliary capacitors. Key resistors are AB or Philips brand. The potentiometer is an ALPS 42-type dual 100KA.
◆ Multi-stage C (Capacitor) L (Inductor) R (Resistor) C filtering ensures a high signal-to-noise ratio. The inductor is a 5H 350MA high-quality oxygen-free copper EI core inductor.
◆ It adopts a 200W EI105×55 power transformer (code: 1055014). The transformer is made of low-temperature-rise H50 annealed silicon steel sheets and oxygen-free copper wires. The matching output transformer (model number: OP964513) is a 5.5KΩ 60W push-pull output transformer, fabricated with Japanese Z11 silicon steel sheets and oxygen-free copper wires.
◆ Coupling capacitors utilize Sprague film copper-pin capacitors, delivering rich and mellow sound with delicate and transparent highs!
◆ This amplifier set comes standard with four Shuguang 6N8P tubes and four Guiguang KT88 power tubes. The unit employs fast-recovery MOSFET diodes for rectification.
◆ Point-to-point wiring follows a single-point grounding design, using 1.6MM thick copper wire as the main conductor. The component layout is rational, resulting in extremely low background noise and facilitating easy component upgrades or replacements. All capacitors are soldered on the top layer.
◆ Unit dimensions: Width 220MM, Depth 385MM (including speaker terminal length), Height 240MM (including tubes and feet height)
◆ Net weight per unit: 12 kilograms
◆ Chassis material: Top and bottom plates are made of 1.5MM thick stainless steel, with the bottom plate featuring a grid pattern for effective heat dissipation. The wooden frame is crafted from solid red walnut, not veneer. Wood thickness is 20MM, ensuring sturdiness and resistance to deformation.
