JOLIDA JD 9 II Vacuum-Tube MM/MC Phono Preamplifier

JOLIDA JD 9 II Vacuum-Tube MM/MC Phono Preamplifier

PREOWNED - FULLY TESTED - INCLUDES ORIGINAL POWER CABLE, MULLARD 12AX7 TUBES (30 HOURS)

If vinyl is a source of enjoyment, then 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 a robust voltage regulator, upgrade output capacitors and changes to the resistor arrays. With dim adjustments and two levels of output, you can easily configure the unit into your system, and then the fun begins.
