• Notes:

  When installing the heat sink, the power tube and the heat sink must be separated by an absolute piece and cannot be connected (distributed). If the output is adjusted to Class A, the heat sink must be increased. Because Class A works in a constant current state, even if it is small At volume, full power is consumed, and the heat of the radiator is also very high, about 60-70 degrees. Don't touch the radiator to avoid soup injury. When installing the machine, it is best to use an exposed heat sink chassis with better heat dissipation. Be careful when adjusting the static current, adjust slowly, adjust it, wait a while, it is not advisable to adjust a few turns at once, so as to avoid sudden excessive static current and burn out the components.
