Design features:
1.The design of the preamp adopts one of the tubes 6N1 6N3 6N6 6J1, and uses SRPP circuit structure. The use of a shed line makes the signal transmission lower loss, realistic, and the human voice closer and more concentrated.
2. The erection line is not only beautiful, but also makes the sound more charming, especially the human voice becomes very close, and the characteristics of poison are vividly presented. Although the circuit is not complicated, the sound is very surprising when it is turned on.
3. In order to make the low noise control better, under normal design conditions, electronic filtering is added, the filament transformer is used separately from the power transformer, and shielding is added.
Parameters: The material used for the whole machine is relatively sufficient. All-aluminum chassis, double transformer, net weight is about 3KG. Width, height and depth: 215X80X240mm (including terminal and bile duct height)
