content: Back when home Internet & Modems were still very young!, I had a WebSite about old valve equipment.I had some examples of (to me) unknown items too. The Site & Provider are long gone!!, but I recentlyfound my old computer-files on another Laptop. Researching back then was a lot more limited. Both ofthese items here, are in storage (I hope!) back in Adelaide, and I'm now living in Western Australia.An 18-kg stainless-steel outer bodied Valve, made by RCA as an experiment. I have no other infoother than the 'simple' notes I put on the photos many years ago!! (Note: That what I labeled as being'Air-Evac' may be wrong, and may be for a separate internal coolant between top & bottom sections)...... I found this covered in dirt, and used as a door-stop within the bowels of and ancientelect/electronics shop in Adelaide, called... 'Robbies' near Port-Adelaide !!I can only assume it was to handle a SHIT load of power !!!These below, are also brand-new & never used. One is 'serial-no-1'. I THINK someone back thentold me they are, (were), probably used for RADAR transmitters ? Again, I know nothing else about them....Any help or knowledge would be appreciated. I've been in the dark for 25-30 years now !!!(P.S. I've more of such interesting antiquities too, but don't want to swamp this post... Glenn.)

content: Sorry no idea, possibly military if acquired in Adelaide!Wow, those are just beautiful! I've been in love with tubes since I made my first 832A push pull RF amp back in 1969

content: I am fascinated by vacuum tube prototyping and its good to see some pictures of a development device. I figure they would wanna consolidate all the cooling and stuff in the final design so you don't have all those fittings etc.

I guess searching for 'V-6469' would have found it !Thanks for the ref info.... Yes, those last units are Magnetrons. I'm saving all that info.

content: If its military the company like LM could have just hired a contractor and gave them a spec for a tube (transfer function) and told them to make it. With those kinds of power levels it would need to be on a warship or some kind of AW'X' plane I think. Or fixed ground radar.Much more powerful then plane tubes I think, I have a early Sylvania TWT used in cargo? aircraft and its not very high powered and air cooled. One of the earliest models of 'integrated' twt circa 1960. I doubt their making pop corn with that thing.

content: Maybe some clues:https://en.wikipedia.org/wiki/List_of_radars#United_StatesSF 10-cm too heavy for intended use on PT boats, but used on larger shipsSG 10-cm surface shipsSJ 10-cm submarinesSO 10-cm PT boatsI think the 100kW is about 10 times too high for a flying radar unless it was some kind of weird secret project.NMV its australia so who knows, maybe it was a secret weapon in some emu war?I wanna guess it was used in the australian navy some whereI found a random ground radar deployed in/around Australia,https://en.wikipedia.org/wiki/AN/TPS-43during the 70's at a similar frequency, it had a peak power output in multiple MW, so I think this tube is under powered for ground use and over powered for air use. Alot of the similarish radar systems used have peak output powers in the MW and fit on 1 or sometimes more transport trucks/chassis.https://en.wikipedia.org/wiki/AN/TPS-44https://en.wikipedia.org/wiki/AN/TPS-75

I've saved that for reviewing !!....NOW, regards thepossible secret weaponuse for anEmu WarI first thought you werejust 'taking-the-piss' out of us Aussies, (not the secret weapon part), but spoke the truth about somethingI was ignorant of !!!!The Great Emu War of 1932!! to reduce the numbers......https://en.wikipedia.org/wiki/Emu_WarThey needed a secret weapon though, because they failed !!!
