Note on 25 Aug 2021 : No more shield can in the pictures. This kit does not includes the JFETs. For JFETS to be included, extra cost of US$95.00 has to be added on. 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 boardband. This kits features the best components : 1. non-magnetic Dale resistors ; 2. Silver mica capacitors ; 3. Highly reliable film capacitors ; 4. Zetex high gain high current linear transistors; 5. Elna Slimic II capacitors( replacing Cerafine with better performance) ; 5. Toshiba matched JFETs ( NOT INCLUDED) ; PCB dimension : Main board - 178mm x 153mm. Module boards : 50mm x 52mm. PCB thickness : 2mm. Copper thickness : 75um ( 4 times normal thickness). Surface finishing : Double-sided solder resist for maximum reliability. The four coupling caps are not included in this kit. Users can pick their favorite coupling capacitors. Operating voltage : DC input +/-18V 50mA per channel. This is a non-assembled kit. The assembled picture is for reference only. We provide schematic and part list to buyers by EMAIL. We do air shipping worldwide at US$8.00. We welcome combine shipping. Track Page Views With Auctiva's FREE Counter Powered by SoldEazy
