ChrisAlbertson wrote:Maybe a 12N05T. This is a relay inside a tube-like glass envelope with an standard tube socket base. It is normally open but the contacts close 5 seconds after you apply heater current. There are other times the "05" is the delay inseconds. These were designed for exactly this purpose, prices are between $4 and $12 depending on where you find one
