Include Preamp_ThreeStack.geo
###Preamp_ThreeStack.geo defines a verticle stack of three pre-amps.
###Preamp positions are still a bit off for simplicity, but the approximations I have made should be good enough.
    ###I've made the pre-amp positions on the sides rotationally symmetric, not a mirror image, like it should be, but the offset is only about a centimeter, so it should be fine.
###Remember, the front of the geomerty is the sun facing-side. The back is therefore the cryocooler side.
