[R-390] Ballast Tubes in Shipment

[JamesMiller]

One or two 390a's I have bought in the past arrived with bad ballast tubes.
But they were presumably working before shipment.  The only reason I can
think of is excessive vibration and breakage of the flimsy filament during
shipment.    Solution?  Before shipping a 390, remove the ballast tube and
wrap in soft foam and in a separate box inside the shipping carton.
