Cool stuff: http://www.synthtopia.com/content/2015/ ... uum-tubes/

I wonder if they will be 12AX7-ish so we can build compact tube pedals.

Yep. I've seen that one discussed on the AmpGarage

Can't wait to get my hands on it

Looks very interesting, I'd like to see the spec sheet and transfer curves.

Buy as many as you can when they hit the open market.

By the middle of 2016 the first ones out of the factory will have MOJO all over them. The early ones will be "better" and you will be a FOOL if you don't hear the difference!

I find this highly interesting. Will these see the light of day? Will they be made available in packages 'normal folks' can use?

what do you think ?


I thinkt it's a brilliant combination of making something that was considered obsolete and expensive using technology that is still used a lot. :thumbsup

Those amps are hilarious! Pretty curious about this nutube thing...

Mostly just curious whether they'll be available at reasonable prices at retail or if they're just going to use these in their own products and get some of that tube gear premium into their margins.

I expect they'll try the latter and then MAYBE the former. They'll probably take a run at selling to select OEMs for a while before you can order them off of Mouser.

Using VFD for audio is a pretty good idea, those are low-voltage triodes after all.
I'm thinking of doing some experiments with that display i salvaged from an old VCR.

Does anyone have a datasheet for a NEC FIP12FM8 or similar ?

Same topic, different thread : viewtopic.php?f=20&t=25799
It looks interesting indeed.
:secret: But VFD from old VCRs have more mojo. Vintage, you know, and most important it lights up !

Really interesting article, I'd love to get a few of these new valves so I can experiment with them, what's even more interesting is that Mr Fumio Mieda san is mentioned in the article, and we all know who he is, he's the guy responsible for designing the Univibe...... :thumbsup


I'm wondering if these new valves will have characteristics similar to the Russian 6N17B, or will they be more like the venerable ECC83/12AX7...... :hmmm:


Great to see that Vacuum-State technology is still alive and kicking..... :thumbsup

Just received in the post 2 samples of KORG NuTube 6P1 triode for a DIY guitar preamp project:

According to the Application Notes the gain is 14dB at 12V and 17dB at 30V, I would like to make a boost channel guitar preamp with some cranked distorted output. I plan to cascade two of them at 24V, should I add additional gain? Opamp or JFET amplifier? Where to place the additional amplification, before, after?
