The bottom noise of this machine is mostly between 0.5 millivolt and 1 millivolt, and the volume potentiometer is turned off. Only when the ear is attached to the speaker can you hear the faint hum. The noise after the volume is turned on is related to the signal line and CD used. The quality of the camera has a lot to do with it, not the bottom noise of the machine.....

​The basic configuration is a simplified version of 4 tubes with a small black volume. The standard configuration EL34 finished amplifier has a net weight of 8.2 kg. The simple and sound circuit designed by dzdn29, 6H8C pushes EL34, adopts dual 290V tube rectifiers, CLC inductance filtering, and the default power of the whole machine is about 10W for super linear connection, and about 8W for triode connection. It can be used to push bookshelf boxes or floor boxes with a sensitivity of about 100W and above 88DB. It is enough to listen to vocal strings. Those who like DJs or loud noises are not recommended to buy. You can buy push-pull tube amplifiers or ordinary power amplifiers from our store. The power consumption of the whole machine is 105W, the power transformer is 160W, and the margin is 55W. After 2 hours of starting, the temperature in the northern summer is slightly higher and only warm in winter, which can guarantee continuous power on for 24 hours. The output transformer adopts 0.35 special Z11 silicon steel sheet imported from Japan for audio, with a tongue width of 22 and a thickness of 45 or 50. The large-caliber floor-to-ceiling box with high actual listening sensitivity is surging and powerful. The mid-frequency vocals are mellow and soft, and the high-frequency is crisp and clear. A Tsai Qin's ferry makes people listen mesmerized, even if it is used to listen to popular dance music. People are shocked, and the strength of the bounce and the clear resolution make people never tire of listening.

The input voltage can be made into 220V or 240V, and it can also be made into 110V suitable for Japan and Taiwan.Remarks can be made when ordering

Small black model: The default configuration is a simplified version of the small black 4-tube circuit board, the size is 27*17 cm, suitable for small spaces such as study rooms, and the power and sound quality are basically the same as other configurations..
