Original poster: "by way of Terry Fritz <teslalist-at-qwest-dot-net>" <zoran.bogunovic-at-gm-dot-com> Would like to know if there is a rule of thumb relative as at what point do you switch over from stationary spark gap to SRSG? Is there a some sort of a criteria, because I was told that if you are running under 2kW of power there is no need for SRSG, just stick with the pipes? Comments welcome
