This is the bare PCB of a high quality amplifier. Similar structure has been used in Marantz HDAM module( please be noted that Marantz has many HDAM gain circuitry and this is just one of the circuits that was named HDAM).For example, it was used in the I-V stage and audio output stagae of Marantz SACD players.Please scroll down to see the last two schematics.

The board features a dual J-FET at the input for low noise and low DC drift. The board is designed such that it can cater NPD5564 DIP-8 package, or other dual J-FETs, or even two matched J-FETs.

The board features a monoblock structure. Two channels are put onto one board with individual ground and power supply connections.

We provide a detailed schematic with components' value by EMAIL to buyers.

PCB dimension : 90mm x 124mm.

PCB thickness : 1.6mm.
Copper thickness : 70um ( 4 times normal thickness !) gold-plated
