Of course this point will be contradicting in places:
The feedback paths should be kept as short as possible which could mean putting parts under the TDA7293 or using SMD (which also isn´t too easy to change) but as you have more practical experience in composites and their sensitivity to layout i´ll stick with your opinion about that.
This is just a draft (parts placing) to whet the appetite and to get a feel for the size of the board and critical areas. You can see the feedback resistors on the bottom layer next to the TDA7293. (this PCB is 80x55mm)
(If you´re ready we will do the layout together, be it next week or in 2 months.)
