[Boatanchors] Crystal Eater?

[Bry Carling]

He did - with some criticisms retracted the following month (grin!)
The articles did not go into detail much but the specific crystal cracker circuit but it is 
the TRI-TET with the plate operating on the same frequency as the crystal.

There are those who insist on using a huge 813 as a single tube power oscillator with a crystal (why would anyone? Beats me!)  I would bet there are two or less hams in the USA trying the odd things suggested in Dave's article.

I stick to transmitters with 2 or 3 tubes at least, and running the crystal oscillator at a sensible power level. Use a sensible "Colpitts" style oscillator or a Pierce, and you don't break the crystals. 
Then they don't get destroyed.  Most home brewers and all but beginners reading Electric Radio would have already known this though.

But anyway, here is Dave Newkirk's better treatise on the subject:

While looking for that, I ran into this rather cool TX construction project on the web also:
