Top 10 Vacuum Tube Amp 116152

Troubleshooting:
Some customers may find the Bluetooth can’t be connected or found. Here is the solution.
1. Power off the M8 and your phone.
2. Wait for 5s and then power on both.
3. If it still can’t be discovered, repeat 1 and 2 and it should work.

Troubleshooting:

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.
