Here is a line of homebrew circuit board that I have made for a amplifier project I am working on. (Which by the way takes forever to comlete 🙂  )
These boards are designed by Dominique F1FRV which have laid down a tremendous effort in designing these boards.
Dominique has done some minor changes to the design since these boards were made, so cards made by his latest instructions will look a bit different from these.
