Bakoon Products' modified version of the DAC-2000 was serviced by the manufacturer and the modifications were verified.
The DAC-2000 was designed to operate with an external clock, but we asked the manufacturer to make it work without an external clock. Of course, it can be used with an external clock and capacitor.
The power supply was converted to an Izukawa-style power supply, a bias stabilization circuit was added, eddy current prevention was performed, and so on.
We also purchase the product, so please feel free to contact us for more information.
