The component print

The picture shows the component print of the PCB. Of course you can't use it for anything except for an overview. Please download the pdf-file instead if you want to see the details.

The printed circuit board is made for one channel, contains everything, power supply and the amp itself except for connectors and transformer (or transformers). You will need one or two transformers. Two transformers if each one only has one secondary winding.

The pcb have groundplane on the lower side (not shown in pictures) which is essential in order to get good results.

The solder side

The picture shows the solder side of the PCB. Of course you can't use it for anything except for an overview. Please download the pdf-file instead if you want to see the details.

Almost everyone of the traces are on the component side. The groundplane is very covering, only a few traces on the solder side, see below.

Almost everyone of the traces are on the componen side as you can see. The groundplane is very covering, only a few traces on the solder side. As you can see from the picture above, all power traces are on the left side and all signal circuits are on the right side. Common pratice so far is to mix power and signal just to get a symmetrical pcb but I have put signal quality in the first room and symmetry and pcb looks in the other.

The groundplane mask

The picture shows the ground plane mask. Of course you can't use it for anything except for an overview. Please download the pdf-file instead if you want to see the details.

The groundplane consist of two halfs, one for the power currents and one for signal ground, at the right. The rectifier bridges have no groundplane because there is no need for it.
