2030A HiFi Integrated amplifier in order to solve the problem of small output power and difficult matching of single-tube Class A output, this series of amplifiers outputs power tubes in parallel, reducing the output impedance and enhancing the driving force, while maintaining the warm and mellow sound characteristics of Class A output.

Product features

Advantages of parallel Class A series vacuum tube power amplifier:
First, the working point of class A power amplifier is selected on the straight segment of the characteristic curve, and there is no crossover distortion of the push-pull line, so there are fewer nonlinear distortions;
Second, it will not offset the even harmonics we need like a push-pull machine, so the even harmonic content is high;
Therefore, the sound reproduction effect of Class A machine is very ideal, and the sound quality performance is moist and beautiful, sweet and beautiful, and it has the charm of "multi-stringed piano".
The single-tube class A tube vacuum machine itself has low efficiency, and the single-tube class A efficiency is even lower, so the output power is small, which is bound to lead to the following limitations:
a. High requirements for speaker sensitivity;
b. Only suitable for lyrical slow music;
c. It is only suitable for small listening area.
 

Product introduction

1.The box body is made of 1mm stainless steel.

2.Shielding cow cover made of thin steel plate, sprayed with high-grade wrinkle paint process.

3.Metal knob, silver-plated shield wire is used in the machine.

4.German WIMA, German ERO, Siemens and other fever polypropylene capacitive coupling, cathode capacitor using American Spirgue, ruby Rubycon capacitor.

5.The resistance adopts a mixture red robe and carbon film, and does not use metal film resistance.

6.Gold-plated RCA mount, amber gold-plated terminal posts with anti-oxidation cover.

7.8 large pond capacitors for filtering, double inductance filtering.

8.The power supply cow adopts 0.35 thin sheet imported Z11 iron core 114mm * stack thickness 60mm.

9.The output cattle adopts 0.35 thin iron core 96mm * stack thickness 40mm, layered segmented interwinding technology, all oxygen-free copper wire winding.

10.Both the power cattle and the output cattle are potted into shielding cases with expensive epoxy resin. It can play the role of fixation, shock absorption, insulation, heat conduction and moisture-proof. Isolate chassis magnetic coupling, reduce noise, and reduce resonance.

11.The classic model features mahogany veneer, while the deluxe model features aluminum alloy front and rear panels.
