This is an ultimate incarnation of the legendary preamplifier JC-2, taking a modular board approach.
The projects consists of three boards. The main board contains the coupling, feedback components and DC power lines and features a monoblock structure.
The two modules contain the broadband high current gain circuitry for left and right channel respectively.
In our test , when incorporating with our Kubota power supply kit, the preamplifier gives a very refined , detailed sound, extended low end and big soundstage.
On bench the circuit measured to have low distortion and broadband.
Operating voltage : DC input +/-18V 50mA per channel.
PCB dimension : Main board - 178mm x 153mm. Module boards : 50mm x 52mm.
PCB dimension : Main board - 178mm x 153mm. Module boards : 50mm x 52mm.
PCB thickness : 1.6mm.
Copper thickness : 75um ( 4 times normal thickness).
Surface finishing : Double-sided solder resist for maximum reliability.
This is a kit of bare PCBs only. T
