A Series Of Tubes!

This page is the area where I explain some of my projects I am currently working on, as well as those that have been completed in the very recent past but are relevant still. Any questions about them are welcome and can be submitted by way of the feedback page and will be answered in some way or another... Through the years I have collected a lot of neat vacuum tubes, vacuum capacitors, voltage regulator tubes, ion gauge tubes, mercury rectifiers, and other strange things. Update: due to popular demand, and despite my own desire to avoid this, I have renamed this section as "A Series Of Tubes!" Here is the datasheet bank for my tubes, tubes I want, and other commonly used tubes.

2 boxed unused and 2 used Eimac Y-427 tubes (special version of the 3CX100A5), a Sylvania 7F8, an RCA 5U4, a used 0D3 voltage regulator and an unused 0D3 in its box, and an unused Amperex 5651. An argon-mercury wavelength tube, an unmarked unknown tube (a voltage regulator probably, because I tested it and it's full of argon), my Eimac 304TL, and two Sylvania 6X4 tubes. My Eimac 3CX10000A7. The high voltage DC supply that I fixed and outfitted with a 4-65A tube, seen here hard at work. Two Eimac 4-440C tubes with sockets, with my Tesla coil in the background. Eimac 4-65A, GE FP-54, Amperex 6907 with socket, and Leybold-Heraeus 555 80 Br 2. Eimac 4PR1000A with completely original chimney, socket, and fan assembly. Testing out the filament before connecting the rest of the 4PR1000A tetrode coil. A pair of (somewhat rare) 812A transmitting triodes, a pair of 4CX250B transmitting tetrodes, a Bomac 3C45 hydrogen thyratron, and two tiny pairs each of Raytheon CK512AX and CK526AX pentodes. Westinghouse iron wavelength source, thallium source, and krypton source. Amperex 12AX7 (with a little picture of a tube playing a trumpet on the side), two RCA 2X2A rectifier tubes, a Nation Union 2C53 high voltage triode, a CBS 0B2 regulator tube, all of which are in front of a Hamamatsu R878 PMT. Also, again, there is a 872A mercury vapor recifier in the back. This is my Hughes Aircraft Company 912H traveling wave tube. It's pretty awesome from 30GHz-40GHz.

Varian ion gauge and 2 mercury vapor rectifiers, one of which is in many of the other pictures. My klystrons. The EM-1188 are reflex klystrons which I know little more about, and I am currently looking for a datasheet for. All of these are from Varian. In this photo: EM-1188 in mounting with waveguide, VA-58, X-13, EM-1188, VA-6975/VA-203B, another X-13, VA-203B My 3CX10000A7, one of my 872A mercury rectifiers, my 50000 Gauss superconducting magnet, and my Litton L-3928-51 traveling wave tube. On the right side is a magnetron that I am planning on doing some wicked experiments with later. My new QK-60, two new 2J51 mags, and of course the giant 4J51. Also thrown in there for comparison are two commercial microwave magnetrons, one with the permanent magnets and heatsink fins and one without. Me talking about my giant magnetron I'm holding. It's a Western Electric USN-CW-4J51 magnetron, operating between 900MHz and 970MHz, at 275kW. It is the same as the 728A tube. This is some of the rest of my tube collection, in my living room, waiting to be sorted through. This is our old Atwater-Kent model 10A breadboard radio from 1924 with two UV-201A triodes from RCA. The second tube in the background is laying alongside the board, and is missing its socket, although the tube itself still has all the wires and is not ruptured. Westinghouse vacuum capacitors from 1945 and 1944, and a Lesker ion gauge. You can see the green uranium glass in the vacuum capacitor on the right, apparently. A couple of my new additions... A Sylvania 811A, a very common power triode for building tube coils, two Amperex 866AX Hg HWRs, a huge ITT 5949A hydrogen thyratron used for very high-power pulsed radars and crowbar switching of extra high-power circuits, and a high-power, water-dissipated xray tube from Machlett with a heavy tungsten target and a 0.5mm beryllium window. Two broken high-power xray tubes I got from a box of things to be tossed out at work. Just goes to show you how wasteful physicists are, when they will throw out things that they know have large beryllium planchet windows. How can people have such disregard for awesome stuff? A photo down the inside of the first xray tube, showing the scoring on the metal target (probably tungsten or some other target metal). You normally can't see this at all, since the high-vacuum glass and the cathode block view of it. A photo down the inside of the second xray tube, showing the scoring on the copper target.
