Push-Pull in AB Class Mode : working in a 2x40 watts push-pull system in AB class, working in triode mode. Based on 4pcs*EL34 power tubes and 2pcs*12AX7 control lamps (ECC83) and 2pcs*12AU7 control lamps (ECC82),the amplifier reproduces a very even sound, without any coloration.
The Yaqin MC13S is known for its excellent sound quality and the unique “tube warmth” feeling it provides. Its simple circuit design may lack some advanced features found in more expensive amplifiers, but this minimalistic approach contributes to its high-quality sound reproduction. The amplifier’s circuitry is based on a proven and reliable ultra-linear push-pull design, which has made EL34-based integrated amplifiers popular among tube amp enthusiasts who appreciate value for money.
The Yaqin MC13S is built with high-grade components, including circuit components sourced from reputable Japanese, American, and European companies. These components are known for their superior quality and are favored by audiophiles. Additionally, the amplifier features high-quality transformers, which play a crucial role in delivering clean and accurate audio signals.
Well-made Quality:The Yaqin MC-13S is known for its well-made quality and robust construction. Its chassis features a brushed anodized aluminum front panel that is 10mm thick, providing a sturdy and durable build. Additionally, the amplifier includes two anodized aluminum side panels that are 4mm thick, further enhancing its overall solidity. The use of high-quality materials extends to the top and bottom covers, which are made of steel.
More affordable Price :The Yaqin MC-13S is often praised for its exceptional sound quality, especially for its price range. Being a class A integrated amplifier, it utilizes tubes to produce a warm and rich sound that many audiophiles appreciate. While it may lack some of the extra features commonly found in higher-end amplifiers, its primary focus on delivering high-quality sound makes it a popular choice for those seeking 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.
