If possible change mounting position on heatsink so that more solid & better heat transfer
Please tell me the sound review latter okay?

Just go to the store link in the top navigation bar. Click on the A/B amp and you'll be able to download the BOM, build guide, etc.

Thanks, I know that.
The question is related to the material used to fab the PCB itself...FR4? thickness of copper?

Thanks Mark,
Yes, hope to build it this year, still have a number of unfinished projects that need attention and also need to do the PSU including transformers first for this "Badger" beast, the good thing is that I have some nice and big DIY casted heatsink for this one.

Tony
