That or a separate board like Justin did, but that makes less sense for a solid state amp. I'm not sure what to recommend, other than try it. I've looked long at a lot of the device clip mounting methods (which still requires a 1:1 ratio of holes to devices) but you could look into a single long bar that applies pressure to all of the devices at once. You could even mill detents into the bar to align the devices. Again, doesn't solve the location issue, but might make it easier to build.
