Yes, very interesting. Would like to see how it might be utilized.
Any tubes currently manufactured in the US, Japan or Germany?
Just curious. This looks interesting, I wonder if we may see something like this in the future

The NuTube has been around for a while. It was developed to provide a way to add low order harmonic distortion for Korg’s synthesizers. It is somewhat popular in the DIY community and their are a number of designs available including one from Nelson Pass. The big disadvantage of this product is that it is extremely microphonic, but it does do a nice job generating second order harmonics. |
Those Korg tubes (chips?) look very interesting based on their long life, durability, and low power requirements (less than 2% of a conventional tube). It seems they could be considered as a catalyst for new, quieter tube designs using smaller power supplies. Would it even be possible for them to be retrofitted as a drop in replacement for conventional vacuum tubes? I would be curious to hear from a designer who has a long history using conventional vacuum tubes such as Ralph at Atma-Sphere. |
Company in Valencia, Spain, ATM Audio, makes class D amps (kind of like Nord, Rouge, Apollon, etc.) that uses the korg unit. https://atm-audio.com/class-d-amplifier/ https://atm-audio.com/input-buffer-for-hypex-and-purifi-audio-with-triode-korg-nutube/ |
I guess I would add what does it matter. The design trumps the manufacturing process. A good developer will do the due diligence of the manufacture and conduct follow up quality control checks. So I do not see where this takes place matters. A good tube is a good tube. Actually sad that what you show in your link is the first time in many years anyone has even hinted at upgrading the ancient tech of tubes. Guess we can get a little excited but not over optimistic.

KR Audio makes tubes and amps in the Czech Republic and they are available in the USA. |
KR does make an awesome KT88 and it looks like they will re-introduce a KT150. KT88 is $200 each, KT150 I expect to be ~$450 each. A lot more than Tung-Sols but...at least you can get them. They will develop a KT120 for me but I need to order 1000. More than I am willing to commit to at this point. JJ is obviously Czech republic but I looked and it appears that they are sold out until June. Not sure if they can produce fast enough to meet demand. The other not mentioned here is Emission Labs which is also Czech Republic. Jac will also introduce tubes but you need to have a sufficiently large opening order.

100,000 people died of drug overdoses in the US last year alone. Millions of people live lives of degradation due to drug addiction in the US. I haven't heard anyone let it interfere with their enjoyment of tubes or their favorite TV show or any even less significant matter. In fact, our government threw the border with Mexico wide open to make it even easier for all this to go on. And that doesn't even take into consideration the tremendous suffering caused in Mexico by the drug trade. If you want to start judging people, I don't think anyone here is going to come out looking very good. |
@stereo5 virtue signaling is a disease. Please seek help |
I’m not justifying anything. I was just thinking that if we are going to judge people as insensitive or worse for engaging in enjoyable pursuits while there is suffering in the world, then we are all going to be judged harshly. There has always been suffering in the world and I see no end to it anytime soon. Fentanyl, cocaine and meth are part of a war being waged on the US. If anyone doesn’t understand that I’ll explain further, but I assume that most people know that there are countries and criminal organizations that want to turn the US into a third world country and that they are having quite a bit of success. Warfare can take many forms in the interconnected world that we live in today. |
