Thanks for fantastic information on this.
Does anyone have several thyrites or varistors I can buy from?? Please PM. I was hoping a few seconds would be good enough. Wouldn't this help promote a longer life for ALL tubes, including CRT?? I was looking into this also to limit as much surge current going to CRT as possible to try and extend service life. Does varistor go in power transformer primary circuit, or somewhere a take off in secondary, for a gradual power on for B+ voltages??
