Pretty funny, but you or the originator left Eimac's real address, etc. on bottom of page.

I especially liked the grid leak bleed off valve.

Wow, the Wemac 1Z2Z looks fabulous.  I'll never buy another Umac 606!

Good one!!!

I especially like the "uranium . . . with all the neutrons removed" and the cooling air flow specs.  Gotta get the slide rule out and figure out what cat hurricane that would take.

I did this a few years ago. No joke, twas for real. This winter time permitting I want to try making a low power TX with it. I have started collecting soup can lids for Varcap construction I have used pencil on wood for GR resistor before in projects and have made caps from paper and aluminum pie plates . Time will tell but should be fun.  built a POW radio once regen from stuff found or made. FUN Goal make a working transmitter with nothing but household garbage. If you go to watch it check out the POW radio build I did too .
