Title: Interesting power tubes Post by: WB3JOK on January 05, 2015, 12:31:31 PM This may be old hat to some of you, but the power tube data sheets are new to me...
I was reading an article by the engineer who created the (in)famous Signetics 25120 WOM (Write-Only Memory), and he credits Eimac engineers with his inspiration for interesting data sheets. Here's two of their finest :) https://dl.dropboxusercontent.com/u/85027770/Umac%20606C.pdf https://dl.dropboxusercontent.com/u/85027770/1Z2Z.pdf -Charles Title: Re: Interesting power tubes Post by: W3RSW on January 05, 2015, 12:49:23 PM 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. --A hit a probably was a big seller once upon a time. Title: Re: Interesting power tubes Post by: KA0HCP on January 05, 2015, 01:49:41 PM Wow, the Wemac 1Z2Z looks fabulous. I'll never buy another Umac 606!

Just Saying...

Title: Re: Interesting power tubes Post by: K9PNP on January 06, 2015, 04:32:42 PM 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 . don |
