Product Details:
1. Before opening, you need to connect the tube amplifier to the speaker. It is prohibited to send a signal to the amplifier when the load (speaker) is not connected, or short-circuit the load when the switch is open.
2. If the power supply voltage is too high, the power voltage is too high, the amplifier will cause irreversible damage, preferably less than 5% of the specified voltage. If the power supply voltage exceeds this value, it is best to use it with AC power supply.
3. If the temperature of the tube amplifier is operating, please pay attention to ventilation and cooling.
4. Spill the liquid on the pipe in the casing or close it for a period of time (within 30 minutes).
5. It is necessary to spend about 100 hours to operate the amplifier. When running on the amplifier, it has optimum and stable sound. Therefore, the sound may not be the best of the first 100 hours of use. You can use your own application.
6. If you dont know how to insert it, please contact us before you try it.
Speaker Connection:
All tube amplifiers used in stereo mode: L(left) and R (right) speakers
Usually there are 6 speaker cable connectors. +8L, +4L, -0L, -0R, +4R, +8R
For example, +8L and -0L are used to connect the left 6-8ohms speaker.
-0r,+4r is used to connect the right 4ohms speaker
