MC-5881A tube amplifier tube amplifier fever HiFi high-fidelity high-power amplifier with headphone function

Features of this circuit

1：Using the improved exported 5881A for powerful power amplification.

2：The use of improved ultra-linear push-pull amplifier circuit, so that the low frequency driving force is sufficient, rich tone.

3: The pre-stage is SRPP amplifier circuit and "long-tail" inverted phase circuit, so that the machine has wide frequency response, small distortion, low internal resistance.

4: The transformer is made of imported Japanese audio silicon steel (0.35mm thick) and

High-strength high-quality enameled wire and special multi-layer layered grouping winding process

The frequency response of this machine is wide, high, medium and low frequency sound is good, transparent and powerful.

5: This machine adopts the electrolytic, Philips (MKP)

Philips (MKP) non-polarity capacitors and high-quality high-precision gold resistance manufacturing.

The main channel using imported volume potentiometer, with music background quiet, low noise, no sound coloring and durable characteristics.

6; With volume adjustable headphone output function, you can directly use headphones to listen to the gallows.

7:Cat's eye type bile volume indicator, beautiful appearance, good dynamics.
