Shad,
That is fascinating. I don't know very much about tubes and virtually nothing about VTTC's, other than what little has been available on list lately. Where would you suggest I start on my mission to learn as much as possible about vacuum tube electronics (shouldn't be too different from SS electronics, at least the basics should be the same) and VTTC's? Any special web sites? Any books you recommend? Any help would be greatly appreciated. I'm still building my first SGTC but I'm always ready for new challenges! From the little I have gleaned from the list, it really sounds like you have something really special there. Thanks. Best regards.
