Did I miss anything?
BRCG, from the sounds of it, you have checked everything that needs to be checked. It just sounds as if you have a bad Tube, which does not happen often, but it does happen. Since you have already gone through all of the installation, I would suggest you call Customer Service (1-800-THE-TUBE). They can issue a Return Authorization label for you so you can ship the Tube in for diagnostics, and either a repair or a new unit. At least this way, you don't have to worry about having to go through all of the trouble of undoing all of the work you have already done.
