Acquired national patent, patent number: 201230601303.0 

MC81 AS Amplifier is a split design, divided into two layers. The lower layer of the chassis is a power transformer and is independently powered; the upper layer is an amplification box. The upper and lower layers are connected by high insulation aviation plugs. 

The chassis is made of 8mm imported 6061 aluminum using CNC numerical control equipment. The surface is made of precision oxidation wire drawing. The protective cover and the top cover are made of imported acrylic and can clearly see the internal electronic components and processes. 

The front panel lower voltage meter and upper power meter use Taiwan's precision high dynamic meter. The factory foundry is a fine copper plated enamel. Internal circuit design is concise, rigorous, safe and stable. 

The electronic components used in MC81 AS can be described as high standards and strict requirements: EI type transformers with Z11 silicon steel sheet and oxygen free copper cable wound by hand, Soviet Union military gallbladder FU81×2, US Tung Sol, 6SL7×1, Czech Republic JJ EL34× 2. Internationally renowned brands JENSEN cross capacitors and electrolytic capacitors, Philips high voltage electrolytic capacitors, Japan US high performance resistors, pure silver wire for the connection line, high quality lead free solder. More than 15 years of senior technicians are pure hand welded.
