This is the bare PCB of a super high-end pre-amplifier. The pre-amplifier takes minimalist approach, features a single stage MOSFET class A amplification for best sonic performance. The pre-amplifier can be configured as either unbalanced in/out and balanced in/out. It is integrated with a 128-steps potentiometer comprising resistive networks to achieve lowest noise and distortion.
The board is also DUAL-mono in nature. The grounds of both channels are inherently separated for BEST channel separation.
On-board power supply regulation and rectification is included.
Supply voltage :
- Amplifier section - AC55Vx1 , 1A per channel.
- Volume control section - AC 15Vx2 , 200mA.
This is a PCB for a stereo pre-amplifier.We provide schematic and part list by email ( attached to the shipment notice on the item posting day).
This is a huge PCB of premium quality.
PCB dimension : 300mm x 199mm.
PCB thickness : 2mm, 2 oz ( 75um thickness !!) copper deposition.
