If vinyl is a source of enjoyment, the JD9II is a versatile and easy to use tube unit that is sure to enhance your sound. Based on an earlier circuit we have improved the unit with a larger power supply, the addition of a robust voltage regulator, upgraded output capacitors and changes to the resistor arrays. With DIP switch adjustments and two levels of output, you can easily configure the unit into your system, and then the fun begins.
