Get you an old crockpot and some clean play sand from Home Depot and preheat the sand to a temp that’s good for your glass and that way you don’t have to use as much gas to temper down the heat on glass and you can just dip them into the sand and let them sit while you do something else. Just dip the ends up to your inside ring so you don’t contaminate the tungsten and the heat from sand will last awhile and rise to the ring. Saves time and gas and better for glass no breaking.

So this is an odd thought but something I've seen in light bulbs is the evacuation tube is positioned in the filament holder end, not on the side. That way when the screw base is put on it sorta hides the evac tube remnant. It's a bit complicated though to have an inline evac tube but it might be a good challenge for you and make things a little cleaner looking. All in all though still gorgeous work.

Hello, once more, a fantastic video on the construction of homemade tubes (valves where I come from). Have you ever thought of reusing any of the parts from dead tubes (valves) to construct new ones or attempt to repair dead tubes where they have gassed, or the heaters have gone open circuit? Could you reuse the pins and glass seals from old tubes, re-melting the original tube's glass/pins into your new tubes, whereby perhaps giving you an alternative way of making the glass/pin/connection seals to the outside of the tube? The thought of recycling dead tubes into new useful homemade tubes sounds like another fascinating avenue for you to possibly venture along? Thank you so much for the fantastic videos. Tubes I have, but being able to make homemade ones unfortunately not, I can't even try to make a simple diode due to a lack of facilities.

About at 28:00 why do you use copper? Why not iron ot steel (and nickel plate the whole thing)? Thank you for sharing.

@jdflyback 2 жыл бұрын

It seems like the steel tends to outgas more in the vacuum, I try to only use it where I have to. The copper also acts like a heatsink, it helps to keep the grid cool since it is very close to the hot filament. It would be better to replace all steel used in the tube with nickel which outgasses less but I have yet to find a good source of thick nickel wire.

@AccidentalScience 2 жыл бұрын

@@jdflyback thank you for the reply. In the meantime I finished to watch the video: very nice job. So if I got it right you basically use just a two stages vacuum pump, no further vacuum (i.e., with a diffusion pump). Also I wonder why enlarging the tube, since the grid, plate and cathode seem to fit inside the stock tube as it is. I'd really like to make some tubes but I struggle to find a reliable source of tungsten filaments, and have to find a way to generate oxygen because the borosilicate glass I have really wants higher temperatures. Can't wait for your next video. Thanks again for sharing. Greetings from the Alps, Europe.

@AccidentalScience 2 жыл бұрын

Oh another thing (sorry for all these questions), what material is the plate made of?

@jdflyback 2 жыл бұрын

Ask all the questions you want! I use a 2 stage edwards e2m1 pump. It supposedly can pump below 1 micron but mine is worn out and I am lucky to get below 20 microns. The real high vacuum pump is the titanium getter, which surprisingly seems to be able to raise the vacuum from hundreds of microns to below one. it really is amazing what it can do. The tube itself does not need to be enlarged, I just think it looks better and it allows more freedom in positioning stuff inside the glass. The plate is made from nickel sheet from an old vacuum tube. I get my tungsten from a seller called prommark on ebay. He sells a bunch of different metals so be sure to look around his store: www.ebay.com/sch/i.html?_dmd=2&iconV2Request=true&_ssn=prommark&store_cat=0&store_name=prommark&_oac=1&_nkw=tungsten%20wire

Very nice, but I only watched 20 minutes so far :p I did get this yellow color when I make bead seals and it worked. But it has a lot of bubbles in the seal. Never got your sealing method to work. Any ideas how to get rid of the bubbles? heating it longer, or doing something else?

@jdflyback 2 жыл бұрын

Do whatever works to get the yellow color, stick to bead seals if they give that color. To avoid bubbles on bead seals it is important to not heat the whole length of capillary tubing at once, but to start from one end and work your way to the other. This allows air to escape from the open end while the other is being fused to the tungsten. If you are already doing that then I would try giving the wires an extra heating with the torch right before you seal them to try to drive any trapped gasses out. I think the reason the bead seals are working is that they are a smaller mass and are easier to heat up to a higher temperature. We are both using air-gas torches and pyrex really needs oxygen to work it effectively. I sort of get around this by heating the seal for around five minutes in the torch and by making sure the tungsten is close to the surface of the glass where it is hottest.

Hello, I have watched videos on KZfaq on early electronic instruments, such as the Theremin, Ondes Martenot and Trautonium. I am wondering whether hand built triodes may have special tonal properties, which would make an Ondes Martenot or Theremin sound better than a transistor instrument. Imagine Rock and Roll with no Marshall Stack. Perhaps you could restore such pioneering instruments. If you can build a basic TV, then an oscillator circuit should be achievable.

Circuit is "Induction Noobheater" by Marko. KZfaq deletes links so i cant share it. It does show up in a google search for me. Center tapped coil of conventional ZVS driver is replaced by a single coil and two inductors going from each fet drain to the supply positive. IRL540N mosfets work the best for me. Adding a separate gate supply helps. I use 3X .15uF polypropylene capacitors in the tank circuit. Circuit runs at 300kHz.
