Цитата: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 features audio unbalanced in/out for most source and power amplifier. 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. Each amplifier channel has its own power regulation circuit too.

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 : 212mm x 197mm.

PCB thickness : 2mm, 2 oz ( 75um thickness !!) copper deposition. Surface is gold-plated with two-sided solder-resist coating for maximum durability.

Новая, не тронутая, когда-то покупалась на e-bay. Без радио элементов.
