korg nutube. Interesting

I'm sure at some point this technology will be used in a guitar amp, or maybe some sort of adapter to use them in place of existing valves.  It's certainly interesting

Ah, it seems they will probably appear first in Vox amps (not surprising, since Korg owns Vox)  early next year

Will be interresting to see how this works out. Naturally I am sceptical about how good they sound for guitar applications, but for clean classic audio applications I can see them work.

If they are half decent they have the interesting potential of creating usable tube amps that can fit in you pocket, which could be pretty darn cool.

Absolutely amazing minaturisation!!!! 

In Japan you can buy values at the local electronics market, so they still love them there. It won't belong before these are used I think.

That will be very interesting.

[AndyR]

Very interesting indeed.

I wonder a) if this an actual vacuum tube (the copy is confusing to me) and b) if so, how it compares to other micro-valves like the Nu-Vista valves...

[JacksonRR]

Skeptical as well. If they don't produce a product that's 100% analog(forgiveness for true-bypass digital reverbs, delays or using a microcontroller to create different preamps with analog signal paths) and with a valve power section, I'm gonna call shenanigans for guitar usage. Plenty of options if they turn out to be nice though.

seems Nasa are getting in on the act too!  although this is something completely different from the Korg product.  It is interesting though :)

Good reading, Blue. You've set me on a Googling mission, when I have the spare time for it.... Here's a little longer read on the same subject you last posted.

It could work.... why not? I say...

Thanks for putting that up, fascinating to read more on the subject

This is awesome.  I can see room for Korg to tweak these to model some of the more historically sought after (and highly unavailable) vacuum tubes.  As an afterthought, I'm left wondering how musical these will sound and if, at best, they will serve as something just slightly better than a silicon alternative.
