Hey Brad, WOW that’s incredible, thanks for bringing this on your channel! I would definitely like to see a Guitologist video on this one. I had no idea these were around. As you now know from other posts, they retail for about $50. What’s really amazing is how quickly companies are embracing this technology. An Ibanez “nutube” screamer, Vox has it’s hat in the ring, Pete Millet has several circuit designs, Headphone amp, pre amps, etc. I think your right, we’re going to see a lot of these in the future. Thanks for the heads up !

Cool beans! I look forward to hearing more about these. Thanks for the introduction!

Thanks for the information! I'm interested to see more on these "tubes" for sure!

I was doing a little bit of reading up on these and they basically have to have a buffer before and after (depending on the load characteristics of the intended application). However, there's nothing stopping you from using a d-class poweramp after it either for a high output amp. What I find interesting is that you could potentially use 1/2 the nutube and feed it back in to the second tube for distortion. Then run that output into a mosfet output stage. Ibanez also re-released the tube screamer circuit with one of these in there (probably replaced the op-amp/diode circuit with this). The micro-phonics might be hassle if you knock it.

Can't wait for the next vid about this. Been following this little tube since it was announced and haven't seen much use of it besides a simple amp for headphones and such. I've been meaning to buy it but I don't have any experience with electronics. Hopefully this year will change. Bought a breadboard and some cables to learn and hoping to jump on creating something for this tube.

HEY MAN, JOHN HERE. YOUR VIDEOS ARE VERY COOL AND INFORMATIVE. I JUST GOT THE VOX MV50 HEAD YESTERDAY AND IT HAS THE NUTUBE TECHNOLOGY YOU ARE TALKING ABOUT. I WILL ADMIT I WAS VERY SKEPTICAL B/C I'M INTO TRADITIONAL TUBE AMPS AND JUST A JUNKIE FOR GOOD TUBES. I WAS BLOWN AWAY BY HOW WELL THIS LITTLE 540G/1.19 lb HEAD SOUNDS. THEY ARE AVAILABLE IN 3 DIFFERENT MODELS AC, CLEAN,& ROCK. I GOT THE CLEAN MODEL. I WAS TOLD IT IS BASED OFF A FENDER TWIN, (THE ROCK IS BASED OFF OF A MARSHAL PLEXI AND THE AC IS BASED OFF OF THE VOX AC-30) IT BREAKS UP NICELY LIKE A TUBE AMP WHEN THE VOLUME IS INCREASED AND IT IS TOUCH SENSITIVE LIKE A TRADITIONAL TUBE AMP. I HAVE MINE PAIRED UP WITH MY EHX SOUL FOOD PEDAL INTO A VINTAGE 15' SPEAKER CAB. I LIKE THE FACT THAT I CAN PUT IN ON MY PEDAL BOARD, PUT IN MY GUITAR CASE & IM OUT THE DOOR READY TO PLAY. I WON'T BE GETTING RID OF MY TADITIONAL TUBE AMPS BUT I CAN SAY I'M A FAN OF THE NUTUBE TECHNOLOGY.....CHECK THEM OUT.

I’ve just discovered your channel and I’m loving the videos. I was thinking about building a pedal this year, which will be a challenge for me for sure. It would be cool if you could do a video about it for beginners, I think a lot of people would appreciate that. Thanks for the awesome vids!

Korg been using this tech in the Vox mv50 amps. If you do get a NuTube sample,you might also get one of the Vox mv50 amps to do an A/B test to see how your home built NuTube amp sounds.

Oh okay. There are a few different versions that are voiced differently, I know my local guitar store have all of them set up for people to try. It could be because that modal that you use didn't like it. I don't know. It is still new tech, and have not been as explored as the conventional tube amps.

Thanks for the explanation, Dale! :)

Another great video Brad! Thanks.

PLEASE DO A VIDEO OF YOU BUILDING AN AMP WITH ONE. KEEP UP THE AWESOME WORK!!!!!!!!

Just wanted to say I enjoy your vids here on YT though I don't comment much..I resonate with the country common sense you seem to bring in making these things. Have a great new year..blessings to you and yours

The Andertons Music Co youtube channel has a video where a Vox guy talks about how they work and some other things, you may be interested in watching that

Yes, try to get a hold of one. I'd like to see what can be done with one of these. Are they cleaner than a 12AX7? Would it make a better headphone amp than a 12AX7 based amp? Can it be used to build a preamp for a guitar amplifier? I'd really like to see what could be done with these.

Very interested on this. Keep the good work.

I have been very interested in this device since I heard about it a while back. Vox has already released a commercial product using it as a preamp section in a 50W hybrid guitar amplifier. I would love to see a video where you show the challenges involved in designing a guitar amplifier or pedal using it. Go get 'em Brad!

great ideas, cant wait to see what you do! be great for the channel!

Very interesting. Thanks for the information!

Wow, this guy knows a lot of stuff, like how tubes are constructed. Well, I guess if he fixes amps then he would know about tubes, but surprisingly, I have never really studied the in depths of tubes, as I never have had a need to know that information, other than just for basic learning. Actually, I think I am starting to remember some of those grids from learning videos from the past, but this video and this nutube inspires me to learn more. Thanks Guitarologist.

Most interesting Brad, let us know how you proceed with this . Keep up the good Work.

I'd love to see you demonstrate the possibilities of this technology.

Go for it ! it would be very interesting to see what you could do.

We would all like to see you experiment with one of these. I'm highly skeptical, as it is hard, if not impossible, to beat the ancient vacuum tube! This almost feels like the late 70's early 80's, when a lot of big manufacturers were going solid state to save money and supposedly improve sound and efficiency. Time will tell... Thank you for posting these videos, very informative!

I have been hoping for to see some guitar related project with nutube. One vote from here!

Man, I recently got into dabbling in pedal/amp electronics now I'm almost wishing I could get my hands on one of these to see what I could come up with. I like how they gave some good examples of application. Also would be cool to cook up some new sounds using this technology.

Man I would love to see some more of this stuff. I've recently been looking into this myself. They are available as well as PCBs for circuits on Ebay

I hope they send you one. I am in Japan right now so I will try to see what I can find and let you know.

Interesting... I suspect this is one of those items that could produce a new tone... If we try to recreate existing tube sounds, it might disappoint but if we try to create new tones it may offer something that doesn't yet exist... I could be wrong and maybe it will be an almost exact replacement for the tubes we know and love.

This has been in the market for a bit now, but I would highly embrace these kind of solutions! It's exactly what we need and I personally love the kind of innovation. The only downside is that they are pretty pricey unfortunately. I have always wondered why tubes couldn't be in a smaller and more efficient package.

Hi Brad ,I'm sure you've seen the Vox MV50 ,maybe you could design a 150 or 200 watt amp that is tube powered by these little tweezer Nu - tubes, it might take 15 or so of them.But the look you'll get setting up when you whip out this tinyTerror size amp and plug into a full stack powered by this thing! And you could make effect pedals by using the nutubes . Great review ,can't wait to see what you build. Peace

Just watched a guy ramble on about the extreme details and specs of a chip, 90% of which i didn't understand. More like this please. :)

Interesting subject Brad. I hope you can source one. Looking forward to the video.

I say go for it, Id be interested in following along,, keep a parts list please!

I would love to see you build two identical circuits, one with one of these and one with old school tubes, then do a sound test.

Before trying these, I think you should look into Subminiature tubes. Those are really fun to play with, and they're pretty affordable to buy in lots. If you want some recommendations for types to look for, let me know.

Very cool, it was interesting I was looking into these things as well. I know Vox Amps have been releasing small little amp heads like their MV50 which have Nutubes in them.

I hope they send you one. Would be very interesting to see what you can do with it. I wonder if they have one that could be used as an oscillator for a radio.

You've got my interest! Go for it!

Brad, you did it again. Bringing new ideas to light. Are these enclosed in glass? Are they shatter proof? Is there, or, will there be a power tube version? It seems a 6V6, 6L6, EL34 type would be needed to be a complete circuit. Maybe the powertube type would be designed to couple to the speaker without an output transformer! Like some SS do. I mean if these tubes sound as good as conventional vacuum tubes, this would become the new way to make amps. Small, low power requirements, less weight and heat, smaller transformer( only need a power trany) all that transistors aspire to,with vacuum tube tone, it's a win, win situation! We will see......Thankz

awesome stuff get onto korg im sure they will send you a sample would love to see a simple amp made from this and can you make it so u can change the voltage to see what it does brad

Nice video, Brad thanx:) I´ve seen these at the musikmesse 2016 korg booth, and had the time and luck to talk to a tech about this thing, they wanted to do something small using available technology (VFD-displays in this case) without a need for a high voltage and alter it in a way that it can be used as an amplifier. For a big company like korg, it´s a complete other situation, you need RoHs, WEEE and the whole paperwork in order to come up with new products, today. So any thoughs of using old tubes or one still in production are completely out of range, as they never would meet these standarts. So they came up with the already existing VFD technology, with has and approval all these standarts, and that´s why they try to convert it into a working triode. It´s a direct heated triode, so therefore it will be act different compared to the usual indirect heated tubes, we are familiar with. First, you can´t easily hook up the usual cathode resistor in order to lift the potential of it. You would need a center tapped power supply to do this right, if you only add a resistor to the filament (which is the cathode) you lift *both* kathodes and also create a "long tailed pair" in where both cathodes share one cathode resistor and therefore the current as well. The only practical solution would be to bias the grid with a separate voltage, exaclty like the old radios did around 1920th... Second, the filament is the same for both tubes, you practically have only one tube (it looks a lot like the 6C33C russian power triode, only smaller), i don´t know why they done this, but it´s not of any use for stereo, nor two independent chanels. But it could be used as an diferential amplifier, if you add a current source for the cathode.

I am thinking about buying a Vox MC-50 clean amp so yes I would like to see you pursue this.

I'd really enjoy seeing what you can do with it.

They work best together. The hall of the large vacuum tubes, and the clear punch of the Nutubes in tandem.

You definitely know your stuff when it comes to amplification Brad, and that's what originally drew me into subscribing years ago. I know we've not exactly seen eye to eye politically, but I wanna give thanks for the technical knowledge and insight regardless. Hope you are well, and happy belated New Year dude.

i used to work with Nortitake back in the late 80s early 90s. they are the best Vacuum Fluorescent display makers by far. it will be a quality part. It is disappointing that it is a direct heated design though. that puts limitations on applications. I'll wait for the indirect heated version to come out before i design an amp based on it. Filament voltage of 0.8V per section is nice. The thing is slightly less than 2" long by 3/4" side ( 20mmx45mm)

the technology may not allow a different method... any old VFD can be used as a similar triode. Thats simply how VFD is made. You can start your experiments with that, if you wish. Harvest a couple from old VCRs or car stereos and you have your test tubes.

@rebelcat420

That’s my reservation on these as well. Until they are indirectly heated, amp circuits are going to look more like transistor designs than the classic “big 3” tube amps. And with the noise/microphonics issues I don’t see them being used for much more than buffers/output recovery amplifiers (aka “placebo tubes”) and practically useless for gain stages (especially higher gain designs). But I’m taking this like I did “digital modeling” 20 years ago- I see potential, but there is a long way to go!

VFD are essentially directly heated triodes, with very low temperature filament/cathode - you can just see it glow red slightly in a dark room. This is BTW what's shown on the pictures, on the left the horizontal filament line is barely visible at 17mA, and on the right you see the filament clearly glowing more at 25mA. The light emitting rectangle is actually the plate, so no, it's not a "burnt out filament" they are showing. I sincerely doubt they'd modify the technology to provide indirectly heated cathode in a VFD - the whole point of it is that it's low-temperature, low mass and therefore low power cathode.

If I remember correctly the reason tubes and other old electronics are being banned in some parts is because they're so inefficient, I'm glad there's some modern alternative we shouldn't take tubes for granted if they're banning hairdryers and vacuums items everyone uses what's stopping them from Banning tubes(sorry bad English)

Saintier set For use as GP transistors that’s certainly true, but for whatever reason tubes reportedly produce more audio output per watt than does pure solid state. (Assuming power for the two types are reported honestly and consistently; wouldn’t surprise me to learn that tube amp power is reported purely as the output rating of the output tubes, ignoring overdriving and/or pre-amp sections. Never having owned a tube amp I cannot measure input and I’ve never amped my Katana.)

And the green pencil pushing [...strike that, trees are killed for pencils] assholes banning personal appliances and UNSURPASSED MUSICAL INSTRUMENT TECHNOLOGY, aka vacuum tubes, these guys use more fossil fuels than 95% of tube guitar amp players. Besides, we went from billions of 100 watt incandescent light bulbs to their 12 watt replacements in 15 years, so I think we can lay off killing the guitarists prized tube amp that is operated for 10 hours a month on average (across all players)! Bottom line? Fukoff leftist morons.

Korg should send you a few, and you can make a review/test on them! Roadruggedness (thats a word haha) microphonics and how to keep them safe! I would love to see you build a circuit with one of these! i too will email korg to get them to send you some! Keep up the awesome work! Super inspirering and awesome! Thanks! :)

I would love to see you build an amp with these things.

I could definitely see applications in microphone preamps and effect pedals. Putting these in a cabinet with a speaker might be a problem. This is pretty cool, though. There is a guy who made a proof of concept amplifier using florescent displays on Instructables a couple of years ago. Check it out.

I have a small vox beatle amp that has these NU tubes and I was shocked how good it sounds very warn just like tubes. I hope you get these NU tubes and make more videos about building a circuit with NU tubes to prevent microphonics issues. The new ibanez tube screamer using NU tubes and that would be a good circuit to build around the NU tube.

Have you seen the new TS pedal with a nutube?

Odd that they didn't show a splitter circuit using two of these, with one acting as a current source in place of the crappy long tail resistor. The circuit you showed had transistor emitter followers on the input and output (or whatever the FET variant is called) which speaks to the horrible impedance these things have. Tubes have horrible impedances too, but the volts are higher. So it's reason for existing in that circuit is for its distortion characteristics. So put it in the signal chain properly.

So, did you get it? That would be a hell of a video, I wanna hear what you have to say after you test this tech.

Please do look into nutubes. I'm interested to see someone actually work with them and see how they perform.

I'd love to see you do something with one of these.

I would be interested to see what you could do in constructing essentially a valve amplifier from these NuTubes. I have seen a demo of these but only in terms of being used in a pedal going into valve amps which is never going to show whether it works or not in terms of a true valve sound.

Please, get one and do some testing to see it in action :) very curious indeed.

I had this in a Vox AC50 amp. Worked fine.

Very cool, I would like to see what you can do with it.

Exciting if it works out

What kind of schooling would one look into to fully understand what is being talked about? I produce music on a dawless level and I'm looking to look even deeper to have a better understanding of how sound is made and how to control and effect it.

Like others and yourself I find this device intriguing. Of course your obtaining one and putting it into a circuit will let us all know what can be achieved with this little beastie. I'd really love to hear tones generated like others here. I say get one if you can so we can all hate it all at the same time. LOL..

Very interesting . But in the example circuit Q1 and Q2 are FET's. So with 2 FET's how much gain is the Nu-Tube making ? In my single descrete JFET preamp I can get a clean tube like 10db of gain on a 12vdc power.

I would love if you got one and tried to build something, that would be fascinating.

Yes, I'd love to see you muck about with these little buggers... Perhaps there's a way to get the micro-phonic sensitivity to work For us like in some sort of feedback inducing resonant frequency characteristic where somehow physically induced... Well clearly I'm in over MY head but yeah, go for it. And also what about raising the ante like using them in an output stage? cheers

Be nice to see it implemented with a window on front panel so you could see the glow.

would love to see this technology built into a vintage circuit. may be interesting

Okay I might not be the brightest bulb in the box but... @ 12:36 you show a chart for resistors required vs filament VCC. If you exceed the .07 volts to the filament, poof, game over. So instead of a "fixed" voltage regulation why not use a self adjusting system? TI makes an Ic, the TL783, that can run this filament with an input voltage between 6 to 104v. As the Ic can only drop the voltage to around 2v, set up resistors after the Ic to set the final voltage. After the output is set, the input can jump across the map and it will not deviate. It will follow the output not the input. As for current, 700ma should be enough to do the job. Am I missing something? Wouldn't this be safer for the tube giving more flexibility in VCC? It only requires the Ic, a voltage ref resistor and a trim pot. If your worried about current, run two back to back. One to set a max current and the other to set max volts.

The VFD numeral tubes in my old Canon calculator are Noritake itrons!

Someone beat me to it in the comments already, but I just got an email yesterday from Reverb that mentioned a new TubeScreamer pedal using a NuTube.

New technology is cool and all, but as far as the guitar community that uses tube amps, we're stubborn and I doubt it will be embraced. But you mentioned pedals, so that could be a market for these. I'd be very interested seeing you wire up a dirt box or even adapt an existing preamp section (say, a JCM800). Hope Korg sends you some samples.

It's cool that it doesn't use huge Voltages like older tubes

Pretty ingenious way to incorporate modern vacuum tube construction methods of VFDs into actual vacuum tubes. More difficult than making regular tubes in my opinion, but this is the automated fabrication process still in effect. Lower power for battery applications as VFDs were designed for battery powered applications such as calculators.

I am skeptical at the same time, but they are not that expensive, so why not try it out.

Hey cool video. It's this the same technology that was used in that vox video I mentioned in your tube export rant video? It looks EXTREMELY similar, way to similar to be an accidentally infringe on vox's design. Anyway, I'm hyped to see if you can get one or two of these and see what you can make.

It would be cool if you could get one, i wanted to try to get one myself, but i'm too busy with other stuff at the moment to allow me to really dive into this thing.

The tube biasing looks strange. Being directly heated, I think you have a effective cathode bias voltage of 0.35V. The grid bias is 0 to +3.3 with respect to ground (or -0.35 to +2.95V grid to cathode). I'm used to tubes always having negative grid-to-cathode bias. That makes me think this may not behave like a normal tube.

Which tablet was used in the video?

This tube technology was used in Casio pocket calculators of many many years back. I remember they were sturdy way back then and they ran on AA batteries. Attesting to its low power consumption.

I don't necessarily think they are trying to replace standard tubes at all. I watched your previous video regarding tubes, and am not convinced that one person's issues shipping tubes via eBay's proprietary delivery company equals the death of the tube amp. That having been said, the Vox amps that use these Korg tubes sounded nice when I watched Anderton's demo them last year.

Ibanez is putting one in the Nu Tube Screamer pedal. Its supposed to be released at NAMM, to repeat what's been stated here already. I heard the guys at Anderton's talking about the NuTube. They were saying that the EU has green energy standards that vacuum tubes can't reach. So eventually vacuum tubes will be outlawed in the EU.

I don't know if the Korg solution will be the one for the future, but it's about time for a company to come with something to be a little bit more modern and reliable; and of course by keeping the tube behaviour and character that we all love.

wow! Yeh, Brad.Here's Hoppping, Lets check it out

I've never used a vacuum tube amplifier (used solid state has always been cheaper around here), but I think getting rid of tubes is fucked up. Just like getting rid of FM radio in some countries is fucked up.. Thanks for another great/informative video!!!

I wonder if they give a light show when in operation ? If so I'll bet some manufacturer will put them front and center on their product.

Never fix anything that's not broken... So what happens when a bad cap leaks DC voltage across the board to it? There goes the reason we love our tube amps! Although I own 5 Solid State Amps 2 Marshalls, 3 Crates... I always hated Crate Amps until I played this 220 watt amp and I purchased 2 so I could have Stereo using a A-B-Y Pedal. 440 Watts of AWESOME! Crate came a long way since they started. I used to host a Blues Jam and a guy asked me if I wanted to use one of his 2 Mesa Boogie amps and he wound up buying a couple.

There was talk in the 1980s about bringing valves back as integrated circuits. The theory goes is that if you could make a triode valve about the same size as what a transistor is on a silicon chip it would switch much, much faster. They thought it might be the next evolution in computers. Obviously things didn't pan out that way. But now with nano tech....well....
