807 tube
[MEDIA=youtube]xc-J-CiXuNY:87[/MEDIA]

One of my first transmitters was a keyed 807 oscillator. After a few improbable mistakes that didn't kill me I had a tube with a hole burned through the plate about the size of a pencil. That lasted until the crystal(s) couldn't take the current....

I strongly recommend moving on to at least an EL or PL509 and a healthy understanding of and respect for Kill-a-Volt power supplies.

But, I digress...
