Retired electronics engineer with about 30 years research experience. But I learned all the tube making on my own in my home shop! It is really a lot of interesting fun making all kinds of interesting tubes and firing them up when they are done.
Hang on a while longer! I have plans on some really unusual audio tubes just for custom amps! I'll get to them later this year. They end up on ebay so you may get hold of them!
Your vac tube tutorials have been great to watch and learn. Noticed in part 2 you re-used pieces out of old tubes. Is it possible to rehab an old hard to find tubes a little bit or does it change the dynamics of the original tube?
oxy and natural gas. In one of his videos he shows how he uses a booster pump on his natural gas line to increase the pressure to a suitable PSI for running a torch.
Why wait 100 years, check out Jeri Ellsworth's channel and watch her make semiconductors in her home lab. It's funny, It's a similar type of tedium really but less directly observable. lol
Is this standard glassblowing equipment, or is it specialized from The Day? I'm asking as I am curious how much all of this would cost if and when it is available.
+Jeffrey Morrissey All of it is homemade. It costs a small fortune if you buy it from suppliers. Ebay is the best source but even then it would be expensive.
Hi Ron, I love watching your videos! What is that vise that you hold the wires in for welding? Is it something that is made for the purpose, or was it adapted from another piece of equipment? Or...?
Hi Ron. I am Julian from argentina. I love a lot the science phisics and electronics. I am wondered with the tuff you make at home. I enjoy too tube tecnology as a hobby. Audio radio and computing or control too. I am having intrest in make the next step making some kind of homemade tube. From schatch of course. Inc@ndescent lamps filaments etc. No efficiency wanted. Just for play enjoy and learn. The answer is: did You think that were possible to make work a simpe scrappy homemade audion with no perfection at all using a fixture of a standard two stage laboratory vacuum pump to evacuate the experimental device? I hope you were fine an thanks for share your work. Julian valenti.
With the addition of a chemical getter such as potassium metal along with the pump you will be able to get the required vacuum. Now to get some metallic potassium!~
@@glasslinger thanks you! Could it be the metallic bright inside of the ux201 tubes? I will look for some of this getters in ebay. My idea is to build an experimental audion from two extremes of a fluorescent lamp one as catode and other without filament just to fix the plate and grid on its electrodes. Both soldered in the center of the cilindrical audion body. Now i am looking in your videos to get techniques. Again thanks you an i see you in action!
@@julianvalenti This may turn out disappointing! I have found that working with the glass from old fluorescent lamps is very difficult! It tends to crack when cooling. Very careful annealing will be necessary. The bright coating inside 01 tubes is magnesium. They evaporated the magnesium to scavenge oxygen from the residual air.
@@glasslingerWell. By the moment I leave the project. But I am very glad to have chatred with an expert. I will try more tube projects like a theremin. Or somthing funny to play. Thanks to share your experience with me. Have very nice projects!
