re: Tank keeps shutting down.

It is possible that the hose, not the valve, is the problem. First thing to check is for a flow limiter / excess flow device in the connector.

re: Yet another annular -- the Quasi-Argus

El-Kablooey I found this on the web: "Stainless vs aluminum conductivity makes little difference in spheres/toroids (unless you're discharging kA-rms arcs, few do).
