My Magnetek 6332 converter took 27 years but finally died. So far, this new converter has worked flawlessly. Fits perfectly. Smart charges the house battery (flooded) which the old converter couldn't do. If I ever want to upgrade home batteries, the converter can charge lithium with a jumper to change the charge profile from flooded/AGM to lithium. It's very quiet. I don't think I've ever heard any fan noise coming out of the converter, which strikes me as odd as the old fan was noisy. The swap
