This was the Los Alamos Perhapsatron, an early toroidal plasma device, on the quest for fusion power sources. I think the big boxes and studs are the fronts of large capacitors, but they don't look like there are any wires connected. So I wonder if this was an early 'photoshopped' attempt.

It's as if it never existed.  ;)

How about a link John? I'm curious now.

Perhaps  :P

Here's a photo. The toroidal thingy is at the far right...


    :o

I've seen this photo before...

Oh crap, now it will take years again to try and fade from my memory :P

Or, "What has been seen. cannot be unseen".

Step into my transmitter, for my shack is the case!

CHASSIS! Who needs a freakin' chassis! It's the ultimate display of "point to point" wiring construction! ;D ;D

Here's an old report that mentions the Perhapsatron.

Dang it, did I forget to attach the original photo? Here it is without TimTron.

The simple reason that contained, net positive thermonuclear reactions haven't worked yet.
...you forgot.  ;D
 
But the fill-ins from Xxcylpitus made up the difference to expose transgressions.

Today is rivalry day.

..and my local team, non rivalry.

What's the plumbing in the lower left corner?

I tried in vain to find an online photo of a Ham who was pushing the limit for the P.E.P. rating of a transmitter. He built a ROOM sized transmitter that was capable of 2500 Watts. Maybe in ER?? An interesting sort of guy. Maybe it was an all class A design. It was huge and unbelievable.

Maybe you were thinking of W3PHL back in the 60s

Not sure what the plumbing is, looks like some kind of gas manifold. Vacuum pumps wouldn't use such small tubing. I realized that the bolts facing outward with white insulation are holding the yoke of a giant magnetic core together. They are not capacitor studs. The whole thing looks like a giant EI transformer back there. I guess they didn't have credit cards back then, but that scope might have had some wiggles from all the iron back there. He had to use a hood over it cause the camera man was flashing in his face...

He has a push button in his right hand. I wonder if he took the photo.

Yup
I remember the FECES controversy now with input RF power of 600 Watts and his outrageous modulator. Upside down tube and DSB with reduced carrier.
Thanks Steve

Have been told by engineers older then myself of back in the old days it was not uncommon for broadcast stations to have someone build a transmitter for them on site, and of 1 to 5 Kw AM stations transmitters occupying a room in a building where everything would be spread out around the room.
The oldest stuff I know of was back in the seventies when I started in radio and you had to have a first phone on duty whenever on the air and the control point had to be able to visually see the transmitter along with meter readings every three hours. Don’t know if the stories about homebuilt room size broadcast stuff is true or not but would imagine all that sort of stuff went away with type acceptance certificates for transmitters. Also hear tales of Sparta, Bauer and other low end broadcast transmitters that were available as kits for the broadcaster who was not able to buy an assembled transmitter. Have no idea how much of all that stuff is true or not. Would think there must be pictures if it’s so.
The thing in the above pictures looks more like the inside of a submarine then radio, but that’s just me.

Bauer did make a broadcast transmitter in kit form.  It's my understanding that a factory rep engineer would help with the proof of performance of the completed rig.

And I was in that room back then and made it out alive!  This was part of his Ham transmitter, but only one room of it.

THIS is what dreams are truly made of...

And it connected to this antenna - 3 elements on 40 meters!

A bad ice storm took that tower town many 10 or more years ago.  Fred put that up to try and beat out my mentor Harry-W3FDY and it never happened!
