Topband: Beverage Frustrations

[jbattin]

Regarding water in the box ... There is nothing  watertight short of a true
hermetic seal. When the temperature changes, a vacuum builds up inside the
box and it sucks in humid air, that humid air condenses and leaves water in
the box. You need to drill a weep hole in the bottom of the box to let water
out and let it breath.
You are overkilling the waterproofing of the resistors. I mount them on a
1"x7" piece of plastic .... drill holes in the ends of the plastic ... and
it becomes the insulator at the end of the termination wire. I have come to
using fuse clips for the resistors to make replacememt easy. When lightning
hits ... they are going to blow .
