    ? ? ? This machine is a 2A3 / 300B dual-use machine. After switching with a switch, both types of tubes can be used. When the switch is turned to the side of the transformer, 2A3 tube can be inserted, and when it is turned to the panel, 300B tube can be used.?

    Output impedance have 4, 8 ohm and 8 , 16 ohm option ,please note when order ,default is 8 , 16 ohm

    ?? ? ? The machine is equipped with a high configuration, and the standard 2A3SE screen eggplant type tube is not an ordinary 2A3C. Or you can choose a 300B model with PSVANE 300B-n as the standard screen eggplant type. It is also not an ordinary 300B tube. The rectifier tube is upgraded to PSVANE 5U4G. The push tube is still Russian 6H8. The three filter capacitors and two coupling capacitors of the whole machine are made of German Mondofo products, and the cathode capacitors use Netherland axial electrolysis, so you can rest assured that there is no need to upgrade. This machine also comes standard with a built-in pre-stage. The pre-stage has a pass-through function. After the pass-through, it can be used as a post-stage. The power cow uses 114 Z11 iron core, the output cow uses 96 Z11 iron core, four clips and three windings, layers of paper pads, yellow wax between the groups; the wave shape of the output cow is very beautiful, not worse than AUDIONOTE.?? ? ? The sound quality of this machine is warm and delicate, sweet and pleasant. Both 2A3 and 300B tubes can be used. Black seat? is 2A3SE, white seat is 300B-n. It is very convenient to change and experience different sound textures.?







    ?The rear terminals are arranged in 840048, 8-ohm 6-ohm loudspeaker connected to 08,4-ohm 5-ohm loudspeaker connected to 04. On the left is the power switch, and on the right is the audio source selection switch. There are two sets of sound source inputs, which are the same. One is red and the other is white, which can be connected to CD, decoded, etc. Switch with the switch on the right.

    The two thick feet of the 2a3 or 300b electron tube are in the back, and the thin feet are in the front. Don't insert them wrong. Only the thickness of the foot is used as the basis for judging, and the direction of the sign cannot be used for judging. Other tubes have protrusions on the positioning key, which are inserted into the groove of the tube base.


    The switches of 2A3 and 300B are behind the pipes of 2A3 or 300B. When using 2A3, switch to the transformer side; When using 300B, switch to the panel side. Don't make a mistake, it will damage the pipe.
