Awesome video man! Love carnhill transformer sound, i'm about to try my hand at a diy project installing a pair of these VTB2281 in a pro vla ii compressor. Quick question though, what pins or side of the transformer is the input/primary?

I enjoy my EEVblog BM235, which I purchased on Amazon. The EEVblog also has a nicer version called the Brymen BM786, which looks great! Another source for Brymen DMMs is Greenlee, which rebrands and sells them in the USA.

I also have the BM869s and agree that this is hands down the best value. I bought mine from Poland also about 2-3 yrs ago and they shipped it to Canada for me. I own a couple yellow branded ones to but dollar for dollar the Brymen comes out on top. Great vid.

Yes, you can definitely hear the narrowing of the stereo field (transfromer ON), bass becomes small, everything is squeezed in a small mushy ball; no thanks. :))

Hello, next time use real music

Why does the x axis of the spectrum ranges from -630 Hz to 19.37 kHz instead of 0-20kHz. Negative frequencies - is this some sort of bug? If these values were selected automatically, is it possible to override manually? Greetings

Can I purchase one of those boards? Or maybe the file to order the PCB boards?? If so, how much? I can do Paypal and pay for shipping. I'm trying to build a vocal preamp with inserts for tube and transformer coloring. I have the modules, but now I need a switcher like yours which will not degrade signal path.

Thanks for the great video. Are you using these transformers now? And where can you buy these transformers? And for how much?

Its wierd, the Carnhills perfectly capture how music sounds when you're microdosing mushrooms.

thanks for this

My BM869S stopped measuring AC within a year. Sent to service under warranty. They couldn't figure out what's wrong and said the meter needs to be shipped to Taiwan for further analysis and I will have to bear the shipping cost as its not covered in warranty. From my country(India), shipping two ways would easily cost more than what this meter is worth. Decided I will just use the rest of the functionality. Within a month after that, the meter started showing 'InERR' in all the modes and its basically a brick now.

Nice1 .Gem & thank u

Every song seems to have different resuts, for the most part I hear stereo solidification in some tracks and differences in drum transients in the snappy songs. Overall very small changes and some songs no noticeable differences. (lynx hilo driving unity audio the rocks mk2 over here) how are you driving them?

What an experience between the overview and the recording. Thanks for sharing!

The coolest feature for audio people is that it lets you read dBu directly on the display (switch it to dBm and hit range to select 600 Ohm), and the AC accuracy is great.

The unit surely sounds good but I don't get the ergonomics. I think their 232P is a masterpiece because you have a controler for every parameter at hand and can bypass individual bands a/b very easily.

It looks like the reaction time on this 869 is kinda slow.

Any other transformer shootout?

Thanks A Lot! You help me solve my problem, May God Bless you!

No difference.

We need a new video with driving them harder :)

I had no idea what FFT even stood for. I had to look it up.

I have the 2 channel model (1202). I found the zero offset does not work. All it does is shift the vertical. When I scale the vertical it still scales relative to 0-V and not to my offset-V. Does it work on the 4 channel?

Sadly my BM869S stopped working after light use of 2 years. It hunts for input and reads lower voltage and wrong resistance (fuzes and leads are okay). Manufacturer wouldn't even bother getting back to me nor did the sales person I bought it from Europ. I'd recommend sticking to Fluke if you're in North America like I am.

My IGS Tubecore has carnhill transfos on the inputs (and sowter on the outputs)...and this video capture how good they sound. Nice work.

How would war in Ukraine affect multimeter shipped out of Poland? How are these things connected?

What's the Maximum MHz the FFT can measure?

On my iPhone I hear no difference. So … what’s that say ?

this is fantastic bro!!

This thing came up when I was looking to silence my neighbors god awful music. What exactly does this mysterious device do?

First, Thank You! I watched (and liked & subscribed) a while ago and now I’m doubling back. I’m intending to build a mastering console with insert switching to my mixing studio. A couple of quick questions/thoughts: A) Your insert switcher looks a lot like other designs, any reasons or benefits beyond wanting to learn, which is Absolutely reason enough, that you didn’t go with Wayne Kirkwood etc? Any updates or insights to your journey there? Maybe another video? B) I also intend on experimenting with transformers, so we seem to be in sync. I have a pair of Marinairs sitting in a box just-a-waiting. But I have more questions than time. In this video, looks like you wired em up straight through, as if they were Output transformers in a piece of gear. Sweet. So the only “Drive” per se is coming from the Hilo line out and directly back in. My guess is that this level is nowhere near the saturation point of these transformers, any specs or measurements there? Any plans to add a drive circuit that gains into then trims out of these guys, or was the plan to stay pure? And at nominal levels, would most similar trannies from various manufacturers perform about the same, not showing their unique character until driven? I haven’t done any of this, but that’s been my understanding. C) While watching the video I could make out a difference all along, but couldn’t tell if it was a slight maybe .5dB level difference. Then when you did the Null test, the frequency response difference is pretty full range, increasing my suspicion that maybe it’s possibly still level differences we’re hearing. So, 1) how did you go about the Null, or level match in general? And 2) is it still possible for you to level match/null again manually while adjusting for the Maximum cancelation in say SPAN or any spectrum analyzer that lets you / us “see” down below -100dB? In the DAW adjusting by 0.1dB you should be able to find the “most” null, both on the meters but also to our ears. D) Have you measured the outs to ins of the Hilo itself? I’m also wondering how much of what we’re hearing is just going D to A and A back to D, how much is the sound of the Hilo vs any other interface, and then how much is the Carnhills run at that nominal level. I hope all of these questions come off in good faith not criticism. I am absolutely grateful to what you’ve done, and inspired to get back on it myself. Right now you’re my hero. I imagine that the reason you put these videos out and shared your journey and findings is to engage with the community, and you had me at hello. Looking for any insights, best practices, and dead ends you can offer. But more than that, I think I share your insatiable appetite for understanding.

in model 789 they worsened the continuity test, I wonder why?

wow

Bro why did you make a video about exactly what I needed on the exact equipment I needed it on? Your making browsing for obscure information too easy. (Thanks though I really appreciate the time you put into this!)

Did you ever finish this build? Curious to see how it turned out!

Any chance you can provide more information or schematics of how to do this? I would love to create one for my studio. It sounds awesome.

Had a Fluke portable scope but just got this scope today! The Fluke was good for basic stuff but this is just way more useful! Nice video!

Hi, And chance you can show us how wired everything? I really am interested in doing one like yi. Thank you

I just can't imagine why and when I might need more than 3 digits after the decimal point. but i wouldn't want to do without a bargraph display anymore.

Wow they have quite an impact.

I am from Vietnam and I want to order this Brymen 869s to Vietnam, is there any way to buy and send to Vietnam for me?

I have a question, is the Brymen TBM 869 the same as the unit, sold in North America under the group Greenlee model DM860A

Excelente amigo una preg cual multimetro recomienda p microelectrónica RAPIDO muy preciso p chekar continuidad resistencias muy pequeñas bajas todos los tipos d diodos transistores semiconductores frecuencias d onda cuadrada y pulsos electrónicos automotrices y consumos en miliamperes gracias amigo excelente tu video y profesional

So I'm a bit torn and hoping to get some thoughts. I have an old Greenlee DM-20 that I've had for about 8-9 years and had been just fine for the basics uses I would use it for (checking some electrical items around the house, some continuity test/voltage readings on various electronics I would mess with). But I'm at the point where I'm ready for a substantial upgrade with nice features, and am willing to put up a decent amount to get something that will last me for many, many years. My hobbiest interest in electronics has only increased as I attempt various repairs on gaming devices, TV's, and audio equipment. Also wouldn't mind having a good meter to check various items at some Cellular sites when I visit for work on occasion (Not installing anything, more Field Engineering). I have always known Fluke as top-of-the-line and started looking into them, but my recent research has led me to Brymen/EEVblog/Greenlee for getting about the same level of features for much cheaper (though there are some sacrifices with quality/ergonomics). I'm trying to find the right balance of getting more than I would need, but also finding a good balance of features. Every time I dig into Fluke meters, I really want to get one but always find that they're specific in their design for certain applications while dropping some features not needed for that specific use. So it's hard to pick one. All that being said, my initial thoughts are that the Brymen BM869s/Greenlee DM-860A for $250 seems more than enough, but also could be a bit overboard and bulky. There's the EEVblog BM 786, which apparently only has different probes than the non-EEVblog one? Though, I can't even find the non-EEVblog one for sale, and the EEVblog website won't ship to US. So that one may be out of the question. There's also the BM789 that looks nice. Anyway, just going down a rabbit hole of options and was looking for anyone else's thoughts/recommendations.

Ohh, you have to get the Siglent arbitrary waveform generator SDG1032X with this. The scope and the AWG can communicate over ethernet to create bode-plots of phase and amplitude. Absolutely insane and game-changing for audio circuit design and analysis.

Thanks for the video. One question pls: I got one recently. I noticed, during my first session with it, that it adds noise to the signal when the Bettermaker equalizer is engaged. I also noticed that the input and output meters are not active, even when signal is going through it. Is this normal or is there something I could be missing?

I was wondering sir, what was your previews scope? Just wanna know to what we are comparing to...

Great video. Sorry if I missed it, but will this allow say ch1 and ch3 to overlay and allow you to compare linearity between the two? For instance, measure input signal on a device and output of same device. Thanks

hello I find this very interesting I would like to use this technique what do I need to buy to use this coloring technique with its transformers I see that there are cables with a circuit on the right side Thank you in advance for your answer Sorry for my English I am French I used google translate

Greetings from Poland. I bought myself one BM896S 3 years ago, after a looong extensive research and specs comparisons, as IMO the best value on the market right now. After these 3 years of use, i have only 2 complaints: beacuse it is so big, heavy and bulky, it takes a lot of space on the table, and is also unstable while standing. I found out that in fact i don`t need this much precision for a day to day use, and i would be perhaps happier with a smaller some model from brymen. For an all round the house use i cannot recommend enough the brymen BM037 clamp, i find the clamp an amazin feature to just clip it to anything nearby and VFD + precision DC/AC current clamp is another extremety useful tool for field electrician as me, you can hang it anywhere around you and it fits in the pocket, and finds broken cables and cables in walls. For bit more exact readings for precise electronics i recommend a separate DER EE 5000 for LCR (and miliohmmeter), beacuse precise voltage measurements and in fact rarely needed and something like BM231 is plenty enough. But hey, it`s you money and place in toolbox at the end of the day. I reccomend Brymen for value though, no matter what model you choose.
