• Double-sided,thick copper PCB,so the copper pad durability is greatly enhanced by lalated-through hole ( PTH) process.
• Hermetically sealed metal casing transistors used on both small signal and power stage.
• High quality electrolytic capacitors.ERO film capacitors for audio coupling.
• High quality solder with silver content is used in soldering.
• Thick & heavy aluminum plates already mounted on the board( as in the pictures) for easy to interface with heatsink.( Left and right channels are shipped randomly)
