Starting at the inputs/outputs (and the associated coax) can be a really
good idea (and are easily tested). I worked the other direction,
troubleshooting a problem on a module long ago, only to realize ultimately
that I hadn't completed soldering a jack (or something just as asinine).
What a kick in the pants after having disassembled the "sandwich" to inspect
solder points!
