It is not the noise level of the machine itself. Please pay attention to this point.

The simple and sound circuit designed by dzdn29, adopt dual 290V tube rectifier, CLC inductance filter, the triode connection is about 8W, it can be used to push 100W and the sensitivity is above 88DB bookshelf speakers or floor speakers. Users who listen to vocal strings can buy this power amplifier. Users who like to DJ or turn up a loud volume are not recommended to buy it. You can buy push-pull tube amplifiers or ordinary power amplifiers from our store.

The whole machine consumes 105W, power supply transformer is 160W, and the margin is 55W, 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-standing speakers 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. Even if it is used to listen to popular dance music, it can be shocking. The strength and clear resolution of the bounce make people never tire of listening.

Input voltage is 110V, 220V or 240V. Other voltage can be customized. If customization service is needed, please contact us.

Application:
The sound source of this tube amplifier is a CD or a decoder. And it can be used with bookshelf speakers or floor-standing speakers about 100W and a sensitivity of 88 or higher. It is enough for families to enjoy vocal and string music. If you like symphonic music with low frequency and great dynamics, or if your speakers' power is larger and the sensitivity is lower, you can choose our more powerful KT88 tube amplifier.
