<p dir="ltr">Not sure how shipping would work but may make sense to replace the hydro with a new 12v nominal DC hydro and dumpload combo or a rectifier circuit of some kind..Jerry at <a href="http://www.APMhydro.com">www.APMhydro.com</a>(based in southern Oregon) is an excellent resource and may have a solution for you. Best of luck!</p>
