Direct Copy Accuphase E550 AMP Power-amplifier 2.0 Channel 60W Class A Power Amplifier | Электроника

Brief introduction of E550 baby:

This circuit uses the line of Accuphase E-550 Class A power amplifier. The biggest advantage of Accuphase E-550 is the description of sound details and strength. For Class A amplifiers, if the sound is soft and sweet, it is basically the commonality of Class A power amplifiers on the market. Although it is 30W at 8 ohms and 60W at 4 ohms, the driving force is quite large, which is equivalent to the 8 ohm 250W power of ClassAB. It can drive a 30-250W box on the market, but the sound will be better than that of A and B. The kind is warmer and lubricated a lot, this is the biggest feature of this machine.

Product specifications:

1. Output power: 30W+30W (impedance 8 Euro Class A, thrust equivalent to Class AB250W, 30-250W speakers can be connected)

2. Power supply voltage: 100V-220V/50-60HZ (

3. Input interface: dual-channel imported pure copper gold-plated RCA socket

4. Output interface: two-channel anti-oxidation crystal large binding post

5. Signal-to-noise ratio: up to 120DB (error 0.02%, ears close to the speaker, no noise)

6. Separation: up to 99DB (error 0.05%)

7. Frequency response: full frequency 20HZ-20KHZ (covering all frequency bands)

8. Appearance size: 430 × 120 × 315MM (width × height × depth)

9. The weight of the whole machine: the net weight is about 19KG, and the package is about 20KG

Nine highlights:

1. The material of the whole machine: It is made of all-aluminum wire drawing and oxidation material, which has a good hand feeling, and the empty box weighs 7KG;

2. Symmetrical design: All designs of the whole machine are symmetrical, and the overall layout to the placement of components are very particular about electrical characteristics;

3. Dual transformer: each dual-channel uses a separate 500W transformer, the whole machine is a large energy source of 1000W;

4. Filter capacitor: each dual-channel uses dual-row 6 each 10000UF 63V Ina imported capacitors, the whole machine is 120,000UF filter;

5. Soft start board: effectively protect the performance of the power amplifier, improve the stability and service life of the whole machine;

6. Straight-back circuit: filter the clutter spikes in the AC mains to avoid the howling of the transformer because the mains is not clean;

7. Speaker protection: The mirror-designed power amplifier board integrates output speaker protection function to protect users' valuable speakers;

8. Power tube: each channel uses four pairs of Japanese classic Toshiba tubes;

9. VU meter head: VU meter head shows beautiful appearance;
