That's a cool gadget, but for 500.00 USD i'd want something that is more than a dummy light saying good or bad. it'd be nice to know what the tube is doing, how far out of tolerance it is, and in what way. i've never been one to trust anybody trying to sell me something based on the voodooo of it. as somebody else commented- How do you test the tester?

[@Hillbilly_Papist]

it costs $300 alone for them to print Orange on it.

[@riffsnreviews]

Yep completely ! Especially as there's been feedback of them not being very accurate and reading bad tubes as good and vice versa... Which isn't surprising as the tester is just testing the tube as if it was in standby mode, hardly no current or plate voltage going through it, it's a gadget. In other words these are crap, and unsurprisingly didn't sell well at all. Testers like the maxi matcher II are way better but like twice the price... And they aren't the best still not 100% accurate, the amplirex ones are better and even more expensive, like close to 10 times the price of this POS, something like 3k$

Tbh i love the combo of you two. Glenn being the mean old hairy dude as always and Henning being weird just goes so well ! Plus you have a total different approach to tone (which both are right, just different) you have a great overall impression of the gear and a lot of background info by our boths connections. Please keep collaborating whenever you meet guys \m/

[@JonathanFisherS]

Just one note, when you're plugging tubes in that have a base like a EL34 or a KT66/KT88, don't press down on the bulb, press down using the base only. The base is the load bearing surface. Pressing in with the bulb introduces small bends in the wires that will break the vaccuum.

[@maskedsid]

Hey, Glenn! I'm a Reaper user and I recently recorder a few songs with my band. Unfortunately the volume is always very low when I render the tracks, while on the daw it's just below clipping. I read that it's all about using limiters and compression.. is that right?

[@micha-elcleveland1265]

A 10 and 11 test may still indicate a matched set - read the documentation

[@slavesforging5361]

Right!? who does a demo without reading the instructions? weird Glen.

[@allenwarfield9262]

Yes, they're still matched at 10 and 11. People like to complain about Ruby's, but I've used every brand I could get my hands on, and Ruby are far from the worst of new production tubes! Their EL34 tubes are actually quite superb in most Marshalls. If it works and sounds good, why worry about the name on it, and why pay more?

[@JoseRodriguez-zh1vm]

Awesome shirt Glenn!!

[@yaniv-nos-tubes]

one of the best products ever for tube heads it's a shame it was discontinued but i have one...

[@shayamaddex996]

The silvery stuff is ceasium (I think) which is used to absorb any oxygen that remains inside the tube after the air is pumped out at the factory.

[@riffsnreviews]

The silver patch on the tube is where the getter is, it appears during the moment when they fill it up with gas and the getter reacts when they flash it, this happens during the manufacturing process. Sometimes it will happen as well shortly after you put the tube into the amp, sometimes you'll get tubes that are all silver and once they are in the amp for a few minutes most of the silver dissipates except at those points.

[@Loscha]

Saturday could be your chance to pull apart the Revv pedal and show us all the guts!

[@Blackboarder77]

Hey glen, did you forget about part 2 to the Mesa vs Benson video?

[@iamgodbringmecake]

YES! GLENN TO THE RESCUE! Just received a pricy tube amp from an online purchase (uneasy sale by the way. The seller had quite a few excellent reviews and comments by the look of it and the amp itself looks pretty pristine upon arrival. The seller said mentioned that the amp had “new tubes” on the listing so that’s why I decided to purchase the amp he had. He sent me some messages thanking me for my purchase and mentioning how he wished I didn’t buy the amp yet because he still wished to jam on it. He decided to ship the amp off without the new tubes citing COVID and waiting picking up his own equipment. So I have him the benefit of the doubt even through Memorial Day and it’s been about 10 days since I received the amp. He is messaging me and says he sent power tubes on his personal amps behalf but he also mentioned waiting for preamp tubes early on in the messages. Any advice would be appreciated) anyways, I needed a valve tester and this will definitely do the trick! Thanks a ton dude! Saying hello from across the Ambassador bridge!

[@riffedwood5597]

Any experience with Bugera Amps and their 'infinium' line? If not, there are 4 LEDs in the back that show if the tubes are functioning or not. Worked for me when my amp started sounding like ruffled garbage bags, the light was out, so I unplugged it and another tube. Also, it auto biases them supposedly so that's neat

[@DCWelker]

I Love my Trirec infinium.. amazing amp

[@riffedwood5597]

DC Welker nice. I want to try out others, I have the 1960, Marshall classic clone

[@uss.chubmarine]

yeah dude i have 6262 infinium its pretty sick

[@RCAvhstape]

That shirt has Stormtroopers fighting Mr. Meeseeks. How awesome is that?

[@jimhart4158]

Glenn, the silvery bit is called the "getter". It is a compound that I don't remember, that is sputtered onto the glass after the vacuum is drawn (it is in a little cup thing, then they heat it up with RF heating and it gets all over the glass). It is used to collect any left over gas particles. Silver = new. Black/brown = old (I think), and white = air got in, and very dead. Never plug in a tube with a white getter, it could destroy your power transformer.

[@jarrahparry]

My Peavey VK 100 head just started to crackle so it's either the valves or just a capaciter hopefully.

[@pedrogiavani2330]

The silvering on the side of the tube is where the manufacturer magnetically induces a current to burn off any gasses that are in the tube from the manufacturing process. This is a very old technique (see tubes from the 40s and 50s) like the 21JV6 tube.

[@janepeters4846]

[@creeperkilla83]

for recording, how much gain should you have on your guitars? because someone i know of, he put the gain all the way on 10 and then he says more gain is better tone.

[@usta028]

should I change the tubes of my amp myself? I keep reading online that its "dangerous" to change and do the maintance yourself.

[@michellelehky2374]

Only when it's on.

[@slavesforging5361]

There are steps involved in biasing an amp that can get you killed if you don't know what you're doing. There's a few different ways to go about biasing an amp, but they all involve exposing yourself to very dangerous levels of electricity. in my opinion, if you ask this question, you definitely shouldn't be biasing your own amps. for your own safety. not to be insulting. i'm not an electrician either. it's okay. remember, you only need to bias after changing power tubes, not preamp tubes. And Mesa amps don't need to be biased at all.

[@adamfox9651]

Michelle Lehky Not necessarily. Some capacitors will still hold power, even if the unit is off and unplugged. One could end up getting a nasty shock if one is not careful. This was always a hazard with the old TVs, which is why there was always an electrocution warning on the back not to open it up and futz with it if you didn't know what you were doing.

[@skatterpro]

There are actually even a few deaths a year from people poking around in their amplifiers without properly draining it first. Those massive capacitors can store one hell of a charge, definitely enough to kill you, so find information about how to drain your specific amp, and you should be good to go. Changing tubes shouldn't put you in too much of a risk, but it's better to be safe than sorry. I'd still not muck around with biasing though, some amps don't even have trim pots, so you'll just have to get in there with a soldering iron and change some caps.

[@adamfox9651]

Do tube amps have an electrocution warning on the back like the old tube TVs did? (I've never owned the former, obviously, but I have owned the latter.) In this overly litigious society, I'd be shocked-pun slightly intended-if they didn't.

[@GreyManFaustus]

So how do you know when to change your tubes if you don't own this toy?

[@yaniv-nos-tubes]

you wait till you hear that something is wrong. weak power tubes will lose volume, weak preamp tubes will sound muddy with no highs.

[@MK-oz2lf]

Speaking of Orange, I know GearGods demoed the CR 120 head but I'm curious to see what Glenn and SMG can do and think of it.

[@johnwalter6410]

That unit is not used for matching tubes it's used to see if the tube is good or not. The meter that's used to match tubes is completely different and it's a totally different process to read the voltage and amper job the tube

[@ICKY427]

$500 is pretty steep. I wonder if guitar shops tend to have one of these in house so i could just pay em a few bucks to test my tubes. Musicians friend also had a VHT tester listed for $99, it doesnt “rate” tubes, but it gives you a a milliamp reading. Not sure which way is better. 🤷🏼‍♂️

[@rjmcmooseknuckle]

I assume henning isn't getting the editor job for your vids? lmao

[@dzamija922]

Question: Why do people like you stack up like dozens of amp heads and yet we only see you use one or two cabinets? Does the cab offer less versatility as far as tone is concerned than the amp head?

[@riffsnreviews]

I'm guessing because he uses mostly IRs , which is obviously way more versatile than having a couple of cabs, and I'm guessing that when he does recordings for bands, the bands probably bring a lot of their own gear most of the time. Personally i'd prefer having more cabs than heads (and I own more heads than cabs :D )

[@himbo7772]

dzamija922 they probably have one tone they like for themselves and use the rest for the bands that come in. Plus IR's can get you pretty close and it's not worth the time to set up an amp, cab, and mic if you can get a really close tone for something that isn't demo'ing tone

[@ryanwilson5936]

The cab/speaker is what keeps everything consistent. It would be hard to judge tonal differences of several amps by using a different cab/speaker every time. The biggest tone changing aspect of any rig is the cab/speaker. Want a dramatically different tone? Replace your speaker/cab. Pretty much the same aspect when it comes to choosing studio monitors. It would be like mixing every song on a different set of monitors and expecting a consistent end result. Find one you like and stick with it. Glenn has done videos on this exact thing. Using different amps with the same cab then using different cabs with the same amp. The biggest tonal difference is in the speaker/cab. Not the amp. Hence, dozens of amps and only a couple cabs.

[@dzamija922]

Yes but that's exactly my point - wouldn't the money be better invested in a different cab if you want a different tone? I mean if you want one exact same tone, why not just get one cab and one head? I guess what I'm trying to say that if what you say is true (and from my personal experience, it is), then it makes more sense to invest in different cabs if you want more versatility in tone.

[@autobotsNdecepticons]

dzamija922 watch Henning's studio tour video: kzbin.info/www/bejne/pZaVpYampMubpZI. If I remember correctly, he showed he had more cabs in isolation chambers. For my part, I have three amp heads at home but only one cab. I tested the amps on my cab and two cabs my brother owns. Mine has Celestion V30s, his some other brand and model speaker that is meant to have a flatter response, and mine is a 2X12 while his are 1x12. The wood is also different in each. But the bottom line is the amp makes a much bigger difference in sound, particularly if your cabs use the same model speakers and are the same size (like both of his), and especially if you're close miking a single speaker, when all the cabinet and room resonance will basically be ignored by the mic. Plus, cabs take up lots of space, while amp heads are relatively small in comparison. Anyway, my take is that a well designed speaker will just reproduce the frequencies that are pumped into it. (With guitar speakers, mostly those in the midrange.) The amp is what determines what frequencies those are.

[@camtheham13]

i think 11 is for when you just need that little bit more

[@peterschmidt9942]

Would have been good to see some used tubes tested and hopefully some bad tubes.

[@baumansound]

This is crazy. I was going to ask for a video about that yesterday. I just got a new tube amp (used), I hear a hiss/hum when it's at louder volume with high gain, and am not sure if that's a tube problem or not

[@skatterpro]

Do you still have signal? A hiss/hum is normal in high gain, even at a pretty low volume. You might want to invest in a noise gate instead of tubes.

[@himbo7772]

The hiss/hum is the compression of the distortion lifting up noise in your signal. If it's *really* bad, try improving your wiring in your guitar, cables, and pedals. Maybe invest in a hum eliminator because some houses have it worse. Don't get a noise gate immediately because if the hum is really bad, using a noise gate to eliminate the noise will eat into your guitar signal if the noise is almost or as loud as your guitar signal

[@baumansound]

Yes i do have signal, it sounds pretty good. The hum can get really loud, yes, and I don't think it's power. I am in the studio here, no other gear presents noise, only the amp. Do you have more info on a hum eliminator? I have not seen one. Also, since the hiss/hum is on the amp itself, where would the noise gate go? It's not on the input because even with the guitar volume at zero, or cable unplugged, I still hear the hiss/hum. Would it go on the FX Loop?

[@himbo7772]

Edward Bauman hum x is the one glenn has and talks about. If the noise is loud at no volume, perhaps your amp itself might need some servicing. You should put your noise gate after the noisest part of your signal chain. If you have any pedals, see if any add a ton of noise. If you check all pedals and find that the amp is the only possible thing that can make that noise, then put it in the fx loop. If you have no fx loop then there's not much you can do other than perhaps modding the amp for the fx loop and if you're doing that, might as well get a technician to make sure there isn't a mechanical error causing the noise

[@baumansound]

Interesting. The noise is only loud when the amp gets louder, the noise increase with the volume of the master level and while on the gain channel. There is noise when the guitar volume is down, not when the amp volume is down. I have no idea what noise would be normal, and not to this type of amp, to be honest. Wonder if I pigeon holed myself buying something used. The tone is great though. also, which video he mentions the Hum X? I don't think I've seen that one!

[@RemyRAD]

This gizmo has a low voltage wall wart power supply. How the hell is that supposed to deliver 250 V DC, of plate current? Plus it would have been really cool if you had showed how it worked. With a known, bad tube? And it gives you a scale between 10 and 15. You mean, one through five? Add so, the way I read that, on one tube, it scored a one. The other scored a zero. Which is about the quality level of tubes today coming out of China and Russia. Why not try sticking in a new old stock Telefunken and see what you get? So on a scale of 10 through 15. Neither of those tubes were worth a damn. They scored the lowest possible score. They're not worth using. Not worth wasting your money on. Or maybe it's the tube tester? It's a computerized device. Which one does not need. None of the ones in the drugstores in the 1960s & 70s, were computerized. And none of them actually test, what they need to test. As they, will probably sell more of those for $500 each? Then they will of, guitar amplifiers? I think those tubes were called, Ruby tubes. From the embarrassed looks they'll have on their face? For selling such lousy tubes. Oh boy rated, a 10 and a 11. Or a 0 and a 1? You'll know, your tubes need changing. When they don't deliver the punchy sound that they once did. Or if they get terribly, micro phonic. Meeting if you tap on them lightly with a pencil. And it sounds like you're beating on a condenser microphone capsule? It's gotten overly, micro phonic. And it might be time to replace it? But all tubes are essentially, slightly, micro phonic when you tap on them. It just shouldn't sound like you're beating on an, EMT plate. It's time to replace the tubes. When it's nice and fuzzy sounding. And you wanted a clean sound.. Then it's time to replace some tubes. If you can't turn it up to the earsplitting levels you once did, it once did? It might be time to replace the tubes? If you're going to spend $500 for a tube tester? Wouldn't it be smarter to just, stockpile, $500 worth of new tubes for yourself? And then give your old ones to your poor friends and kids. Instead of wasting $500 on a tube tester for a guitar amplifier? Think about it? You might spend $500 to find out that your VF-14 in your U-47, needs replacing? And then you have $500 less with which to purchase one of those. If you can find one for less than, $5000? New tubes will hardly matter in the microphone preamps that have them. If you're into the budget ones like the, APHEX. Why? Because they're not running that tube as an amplification circuit. They're running it at such low voltages. You can't even see the heater light up, the filaments light up. Because they don't. Nope. What you're looking at is a yellow LED, behind the tube. And it's operating at highly depleted, plate current. It's only there to make distortion. Transistors and IC chips do the rest. It's only there to give you tube distortion, in abundance. It's not meant for amplification. But in guitar amplifiers, they are. So, what good is the tube tester for your guitar tubes? When it can't deliver full plate current & voltage with the tester? Oh yeah. That's going to tell you what it sounds like in your amplifier. Glenn, I think you should go back to your school and ask for your money back? They didn't teach you that stuff? And you're a guitarist? I know I know. It's all that good German beer and knockwurst and schnitzel. You're forgiven. Maybe a more comprehensive test with German guitars. Demonstrated along with, German beers? Would be more educational? And which one makes you wail more? I'm sorry. You're disqualified. You already won the, Wail, Contest. Looks like too much schnitzel for you?

This is basically a scaled down version of what they used to have in the drug store when I was kid, back in the middle-ages. Drug store version had more sockets for more types of tubes, though, like what you used to find in radios and TVs.

[@RudyAyoub]

Adam Fox you were alive in the 1500's?

[@adamfox9651]

Rudy Ayoub Heh heh. Those tights and puffy collars itched like Hell!

[@RudyAyoub]

Adam Fox how did you handle the torture

[@adamfox9651]

Rudy Ayoub You referring to the rack and the iron maiden, or the itchy clothing?

@5:20 The silvering is your getter, its a highly reactive metal (usually caesium or barium) meant to pull impurities out of the tube. If the getter is still shiny, it means the tube is still under vacuum, or that whatever low-pressure atmosphere is in there is properly inert. Silvering is not in and of itself bad tube. Getter placement is usually at the top or bottom of the tube, but some may flash from the side, or be oriented oddly when activated. Now, if your getter turns black or crusty white, it means it's reacted with something. That IS an indicator of a bad tube. Unless you are using an extremely vintage tube with a weird getter (unlikely).

[@petegaslondon]

Yup! And when your getter turns smoky white, THEN you know you've got trouble (it means your tube is no longer 'vacuum' !)

[@and1424]

You really do not know what that equipment measures, do you?

[@B3Band]

Well, damn, if I'm gonna take all that time to open up my amp and gets the tubes out, I might as well just replace them at that point. Maybe this would be good for testing the new tubes, but certainly not for $500. Unless that's AUD, in which case it's a steal.

[@GuitarGodgt]

My local music store has a huge cabinet style tube tester that used to be a fixture in appliance stores when televisions had tubes in them. It will test any tube found in an amplifier. Pretty great resource to have honestly. He also fixes old radios and has a huge inventory of NOS tubes.

[@cyber_tano]

Hey Glenn! That's a pretty neat device, it would have cool to see what it messures on an old tube, one of those that it's not broken but still has a deteriorated output. Also, It would be awesome if you made a tutorial about using an SPL meter to not fuck up on volumes, thing that happens pretty often. Thanks a lot and greetings from Argentina

[@Evilwhiteclownpunk]

Can't you just stick 'em on your tongue like a 9 volt battery???

[@ayusharipirala3121]

How would you record metal guitars (no impulses or amp Sims) without using celestion v30 speakers or an sm57? Because that's the usual Speaker and mic which people keep leaning towards when recording guitars, so how would you do it differently? *Sorry for my bad English

[@BigMikeGuitar]

That 1 to 15 scale reminds me of the Groove Tubes rating scale of 1 to 10. Probably the same thing - but what does that mean? My understanding is it represents a softer-harder scale (that's what she said), not necessarily a god-bad thing (that's not what she said).

[@kalidesu]

Cool unit but... at $700 AUD get stuffed. There must be cheaper alternatives. Could buy a good amp and a shit load of tubes for $700.

[@bayouboattrash]

Ruby tubes suck. I had some in my laney iron heart. Was not impressed. Changed them out for tung sols.

[@TheProgGuy]

Great gadget for a working class studio engineer or professionsl amp technician, but i dont see any standard musician buying one anytime soon.

[@neilbeni7744]

The question is how accurate is the orange and anyone doing science does tests more than once before making a conclusion...

[@Tysman909]

For that much might as well get metal conductance tester. Would be more useful for amplifiers cause measure the gain of tube

[@godzilla964]

Great tool for hobbyists and recording engineers, not good for gigging musicians.

[@EthanAndViolaVlogs]

If Stryper came to you and asked you to record there next album, would you do it?

[@Maverick7r]

Hey, I can try this on my Line 6 Spyder amp!!! J/K, lol!!

[@danmatheson5975]

Just a little constructive criticism. STAHP

[@qua7771]

What the he'll is he saying?

[@raysmetaltracks6782]

May want to give that tube another test (plus I believe a 10/11 would still be considered a matched set if I'm not mistaken?). These testers are good for a very basic test, but not known for the best accuracy. I'd actually be more inclined to trust the testers the manufactures are using (if they are being honest, that is - which in my experience, they have been for the most part). The tube tester my amp tech uses is the size of a washing machine. Rather large and clunky back in the day, but better accuracy.

[@jaytyler5741]

Hey Glenn. Aren't you not supposed to touch the glass on the tubes? Kind of like fucking up a headlight with finger oils.

[@VintageSG]

Not applicable to tungsten lamps or general service valves such as those found in radios, televisions and guitar amplifiers. Tungsten lamps run a lot hotter than the heaters in a valve. White hot compared to the red hot of a valve heater, and tungsten lamps have no issues. Also consider that manufacturers use inks on the glass envelopes of tungsten lamps and valves. Ruby go so far as to put stickers on the envelopes of their product range. I have numerous Ruby 12AX7 valves as pulls with their stickers intact after, say, 100 hours of use, and quite a few Ruby EL84 valves with their somewhat charred identifiers still clinging to the glass. Quartz halogen lamp envelopes are a different matter. The envelope is much smaller and the heat of the inside of the envelope is crucial to the tungsten evaporation/redeposition cycle within the lamp. Notice how the envelopes and filaments for quartz halogens are much smaller for their rated power and usually there are no markings on the envelope. Some headlight lamps have a cap of paint on the end of the envelope,. but there's nothing where the envelope runs parallel to the filament. Finger grease does three fifths of smeg all harm to a guitar amp valve. Hope that clears it up for you. Check the Wikipedia article on the quartz halogen cycle for more information.

Hey Glenn, That silver stuff inside a tube is a Getter spot serving the purpose of completing and maintaining the vacuum. When gas molecules strike the getter material (typically barium), they combine with it chemically or by absorption. Thus the getter removes small amounts of gas from the evacuated space. For example, if you crack/break tube's glass envelope getter spot will slowly turn white indicating air leak inside. In some old tubes this spot can have dark chocolate color because of years of impurities absorption. So as long as this spot(s) is nice dark silver color your tube is fine mechanically. Cheers! Phil.

[@XaxSovereignxaX]

SpectreSoundStudios The silver coating on the inside of the tube is the getter flash. It's a chemical coating that's used to chemically evacuate residual air from the tube as well as a way to indicate whether or not the tube has an air leak. The only real time you would be concerned with this silver coating is if it has turned powdery white, which would indicate the tube no longer has a vacuum. To demonstrate it you might be interested in taking a worn out tube (or one you're willing to sacrifice) and break the glass on it and you can watch how quickly that silver coating turns to a powdery white coating.
