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.
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
