Original poster: "Jason by way of Terry Fritz <twftesla-at-qwest-dot-net>" <jasonp-at-btinternet-dot-com> Hi all, I have a 10A variac and I have a 20A variac bruch that I picked up off a friend. Provided that it physically fits in the old variac, does this mean that I will be able to overrate the variac by more than usual?? thanks Jason
