When I was working as an electronic tech at the University of Montana, one of our professors 
had a very, very expensive Phillips research X-ray machine which would intermittantly shut 
down.

That thing had something like 90 tubes in it.

After a long night of digging into it, I found a no-solder joint on a filament connection to a 
critical tube socket in the power supply section buried at the very bottom of the unit, under at 
least 4 layers of wiring.

I was pissed and the professor was pleased.
