subpanel, because NOW is the time to check this front area of
the board for:
Correct parts selection
Solder joint touchup
Wires properly trimmed to prevent shorting
Solder bridges
Correct soldering of controls so their locking pins
fit the corresponding holes of the subpanel
No loose strands of coax braid shorting to other
points on the board
