• The Yaqin MC13S offers excellent sound quality with a warm tube feel. Its simple circuit design lacks unnecessary features commonly found in more expensive integrated amplifiers. This amplifier's simple circuit design delivers high-quality audio. This amplifier is built on a tested and proven ultra-linear push-pull design, making it a popular choice among budget-conscious audiophiles who appreciate the sound of EL34-based tube amps.
• Operating in AB class mode, the amplifier functions as a 2x40 watt push-pull system, employing four EL34 power tubes and two 12AX7 control lamps (ECC83) along with two 12AU7 control lamps (ECC82). This configuration enables the amplifier to deliver a consistently balanced sound reproduction devoid of any tonal coloration.
• High-grade Components: Many of the circuit components are sourced from renowned Japanese, American, and European companies known for their audiophile-grade products. The volume controller is a reputable brand, and high-quality transformers have been utilized.
• Well-crafted Quality: The well-crafted chassis is constructed with a brushed anodized aluminum panel measuring 10mm in thickness, two anodized aluminum side panels measuring 4mm in thickness, and top and bottom covers made of high-quality steel. The four line inputs, six banana speaker plugs, the volume control, and the input switch are of exceptional quality. High-quality STALLOY transformers have been utilized.
• More cost-effective pricing: Yaqin MC-13S is widely regarded as one of the finest class A integrated amplifiers, particularly for its competitive price. By prioritizing sound quality over additional features commonly found in pricier amplifiers, this tube amp offers a more affordable option.

please note for the orders from USA, Canada or Mexico, the AC voltager is 110 volts, insteadf of 230 volts. The reason why the amazon page shows the AC voltage is 230 volts is that this product is also selling in Europe Amazon, then Amazon automatically harvested the AC voltage 230 volts.

YAQIN MC-13S is considered one of the best class A integrated amplifiers in 2021 by review group of amplifier experts in USA and Europe.

The first guarantee to Yaqin MC-13S high-quality sound is the bare-bones and straight circuitry and ultra-linear push-pull design.

The second guarantee is the high quality of components including audiophile-grade resistors, coupling capacitors, and volume controls.

Off all the components, the transformers stand out most. Both the input and output transformers are very high quality. It starts with the oxygen-free enameled copper used in the windings for the transformers cores. It ends with the use of 35-milimeter Japanese steel sheet employed in the building of the laminated stacks surrounding the core windings.
