Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <CHURCHMON-at-aol-dot-com> Hi Johnathon and list , I too am concerned that if I build one of these triggered gaps that I could get back lash from the tank circuit if I come in contact with the dimmer knob. Has any one else experienced any from these type of trigger circuits ? Thanks , Mike Church(CHURCHMON)-at-aol
