Default Help needed to start F3 building


I need some help with planning to build F3 amplifier.

I allready have power supply with 500VA and 2 x 53VDC.

Where can i get PCB:s for two channels?
I have tried to search from this forum and Google for whole day without results.

I also need complete schematic, PCB layout, map for component placement and parts list.

Thanks !

I have build the F3 last month.
Because it is nearly impossible to get some PCBs for the F3 I decidet to make my own one.
If u want to get some pcbs please send me a message. Also can help to get the LU1014D or the output capacitors.
