To facilitate diyers to build this classic preamplifier, we offer a kit, including the board, the input JFET, the matched output MOSFET and the MOSFET on power path.
The exact components to be delivered with this kit are : 1. 2SK389V ( used and 100% verified )one piece 2. 2SJ109V( used and 100% verified ) 3. matched IRF9610/610 two pairs 4. IRF9610 one piece ( for power supply section) 5. IRF610 one piece ( for power supply section) Background of JC-80 amplifier : This is the newest board layout of the legendary JC-80 preamplifier. The original JC-80 was designed by John Curl. John Curl once commented this is the best preamplifier he has ever designed. This revised board version has the below improvement over the old version : 1. The trace and grounding are carefully considered and routing improved. 2. The servo circuitry has changed to lead type components. This allow better, audio grade components to be used on servo section. This is a mono design. Two boards are required to form a stereo amplifier. We do air shipping worldwide at US$6.50.
