Gendex 770 Tube Head FAQ
Is my Gendex 770 worth fixing?
If the arm, mount and control are working, replacing or rebuilding just the head costs much less than a new X-ray and installation.
Do you have heads in stock?
Yes. We keep refurbished Gendex 770 heads on the shelf.
Will my X-ray need to be re-registered?
Some states require re-registration or re-certification after a tube head change. Check with your state radiation control program, and have a qualified dental X-ray technician install the head.
