I have two Sunn amps now that are both in pretty excellent condition. I used to have a model T that had a severely rusted chassis. It didn't hurt anything but I now have a model T that is surprisingly rust free which seems to be a rarity from many that I have seen on EBay. I would like to keep it that way. Just wondering if there is a trick to keep it from happening. I don't store it in a moist environment but it just seems they are kind of prone to rusting. Lastly if it does start, any way to remove the rust and make it look nice again? Seen it on a lot of Sunn amps but particularly Model T's.
