I intend to be a 12 year old at heart until the end.

And on that note, my saintly and overly-patient wife just gave me my present, a first edition of Alfred P. Morgan's "The Boy Electrician." 1913, pre vacuum tube. It shows how to make a wireless receiver with a coherer. There's a chapter entitled "Electrical Appurtenances." Really wonderful!
 
taking what appears to be a perfectly good twin triode and making a piece of jewelry out of it...I thought it is a ray tetrode.

A twin triode it ain't.....looks like a 6CB6 or one of its relatives. They fit the red board, but no one needs to worry there are at least 16 million more of them out there.

Happy Birthday, SY.

Sherri claims that I tend to act more like 17.
