About tube + transistor amplifier
Tube amplifier has its unique “smell of tube”, sweet, soft, warm and listenable voice and good musicality and atmosphere; but its high-
frequency transient response and resolving power are worse than that of transistor especially when listening to symphony.
“Transistor” has the advantages of large dynamics, high speed, strong resolving power and strong driving force, especially suitable for
the songs with large dynamics; but it is not soft enough and its high-frequency sound is sharp and dry.
Therefore, front tube amplifier and rear transistor combine the advantages of two amplifier circuits to achieve the idea sound effect
and make you immersed in the happy atmosphere of music.

Description
Troubleshooting:
- Please note that this product is a preamplifier. It is not an amplifier and needs to be connected with an amplifier or active audio devices. Also, it is not a phono preamp and can’t work with a turntable. For noise issue:
- There is a large probability that the low-quality audio cable causes the static noise.
- Please make sure the sound source is fine since tube amplifiers will amplify all sound including the noise.
- Please check whether the tubes are plugged well on the tube sockets or not.
- Devices like routers, mobile phones will also interfere in the audio signal and may cause static noise.
- If your problem can’t be solved, please feel free to contact us. We will be very glad to help you and try our best to make you satisfied.
