Very cool. I like his description of how he found parts for this transmitter:
The power amplifier tubes needed ventilation as well as shielding; that was always a challenge because I had no good source of perforated metal. The black sheet with the round holes actually came from the cover of a car air filter that I found in the trash.
There is a lot more interesting stuff on Nathan Zelde 4Z4GE’s site:

Very interesting! I like the adaptation of the ARC-5 reduction drive to the vernier readout. This is a useful technique for us even now, these (and similar) are still available at the hamfests, and with a little ingenuity, et voilà! Lots of good stuff in this article.
A fine homebrew rig! Thermatrons at their finest!
