2020A HiFi Integrated amplifier with vacuum tube for Home Audio System

  

The 2020a vacuum tube amplifier has high-fidelity HIFI characteristics and a unique taste that makes people feel warm and mellow. This series of tube types are: KT88, 6550, EL34, FU50, etc.

Different tube types have different power and timbre. The parameters of KT88 and 6550 are the same, the tube has a straight shape, mellow sound, open sound field, natural smoothness, and a strong "gall" flavor, which lives up to expectations and can be described as the ceiling in the medium power tube. EL34 small family jasper type, less power, the tube Ya "generation of wind flow", the sound is sweet and smooth, delicate and soft. It is praised as "sweet female soft voice" by European and American celebrities, and the regeneration of "heavenly sound" is really a song of green mountains.

FU50 was originally a high-frequency transmitting tube, now transplanted for HIFI audio, the mid-high sound is transparent and bright, the texture, air sense, grain sense is good, audiophiles give it the elegant name "otherworldly". When connected to the triode form, the frequency response curve is closer to the famous Guts 300B, so it is also called "Little 300B". The output power is large, which is easy to match with speakers of various sensitivities.

It is suitable for expressing vocals, strings, etc. And belongs to a tube type with super high cost performance.

The resistor is mixed with Taiwan and domestic carbon film resistors and metal films, which is warmer and more resistant than pure metal film resistors. The power cattle adopts 0.35 thin sheet imported Z11 iron core, 114mm stack thickness 60mm, and the output cattle adopts 0.35 thin sheet imported iron core 96mm stacked thickness of 40mm, layered and sectional winding. All transformers are potted with expensive epoxy resin in the shielding case, which can play the role of fixation, moisture-proof, insulation and heat conduction, isolate the magnetic coupling of the chassis, reduce resonance and reduce noise.
