Blues Jr, any mods or advice available to convert tube mount pcb to hard wired?

The ribbon cable helps keep things going to the right places in manufacturing, and in repairs as well. Recheck all the wires are in the right places. Close proximity of leads won't hurt in this audio application, just trim them short enough to prevent shorts. I wouldn't let solder get closer then a couple of mm to be on the safe side.
