Original poster: "Luke" <Bluu-at-cox-dot-net> Can anyone tell me what would be considered near the minimum voltage that would be feasible to use for the supply transformer? I have heard of people using 9KV Any one ever use a 6KV or even a 4KV? This is all in regards to a classic design (disruptive I think is the term?). not solid state or magnifiers etc. Thanx Luke Galyan Bluu-at-cox-dot-net
