The operation is particularly smooth. The only included item is the power cable. The power supply has been modified to separate the power for noise reduction in the power tubes and to ensure the safety of the fan circuit. The functionality remains unchanged. Bias has been adjusted. The appearance shows signs of use, but I think it's in good condition for its age. Please check the photos. This is a used item stored by an amateur, so there may be other oversights. Please refrain from purchasing if you are sensitive to such details.
