The main materials are as follows: the transformer uses 27QG0.27MM (the previous H * * Z * * name has long been lost). The high quality iron core CNC winding machine precisely arranges and winds each layer, and the connection is tight and stable, with low temperature rise and long service life. The coupling capacitor adopts German GAD with high consistency and accurate and clean sound. ALPS27 blue case potentiometer made in Japan is used for signal input. The band switch also uses Japanese original ALPS. Each product will match the original according to the sound characteristics, and also consider the temperature, interference, withstand voltage, and power internal resistance of the original in the circuit to optimize and improve. Gold plated tube base, stainless steel screw, pure copper gold plated RCA and terminal. The shell is made of 1.5MM thick iron plate, which is used for electrophoresis, powder spraying and drying at high temperature, and then spraying high temperature gray baking paint. The panel is processed by aluminum alloy CNC, and the full chamfering process does not scratch hands. The surface is sanded and anodized
