Are the same model specifications for different country indicators. Do not place the machine next to the transformer of other machines. Plug in the tube and install the case before powering on.The complete installation of the case screw can ensure that it is not easily interfered. The tube amplifier is especially high-amplified and placed on the short-circuit input. When you open the maximum, there will be a little noise. The original machine will have the same. It is generally not possible to use the volume to the maximum.
If there is obvious noise, first check the tube noise. Replace the position and place the low noise in the front. The negative noise level of the grinding signal base is reduced. The noise of the hand is increased. Please check whether the power line of the home power supply is good or effective.And whether the signal line outside the machine is specified at the high potential end of the shielding layer. The following conditions may cause the sound of the sing to produce a bathing sound. The electrical appliances with poor quality switching power supply at home may interfere with the singing, and the thyristor or energy-saving lamps may interfere with the singing. If there is strong high-voltage electricity outside the house, it will interfere. Singing, too close to the community transformer room will interfere with the singing.
