Acxico Amplifier Amplificador 2N3055 Channel Review

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).
