The original question in this thread was never answered. What amp to build ? I don't know if there is a solid state amp that people want to build. Maybe the Randall RG100 comes as close as anything, but I don't know that anyone has done it. There are a couple of threads about the Marshall Lead 12. Even some PCBs offered for sale.

What you really don't find is a good layout. I mean a layout so you can build say a power amp or preamp on some kind of proto-board. I used to use a PCB program to do layouts, but that software died so now I just do a 2X pencil sketch on graph paper. For help drawing circles, I use a circle template. Attached is a scan of a layout for a power amp. I use three sizes of eyelets. Sometimes I use turrets to mount power resistors up off of the board.
