@@chrisdsouza8685 Thank you very much for your kind words. :) It gives me strength knowing that there are a large number of people who support Mark and our communitys.
If Evans didn’t want anyone poking around inside his preamp then he should have fixed it himself - gratis. That’s assuming he’s capable of fault finding his own designs.
Honestly, even though it's a lame dirty thing to do, the removing of IC part names/numbers would be the least of their worries for me. If I paid £25,000 for a phono preamp, took a look inside, and saw "Op Amps" all over the place amplifying the stages, I'd mush it right in the manufacturer's face with one hand and hold the other hand out waiting for the refund. At that astronomical price, it should be entirely discrete with not an IC in sight.
I emailed the manufacturer the day after the video was taken down and warned them they had a chance to back out of this before it went too far and would end up hurting their brand because I foresaw the EE community on YT and the right-to-repair movement was always gonna stick together……….no response!
@@IanScottJohnston one of the hi-fi forums has a response from Tom Evans about this and it isn't very complimentary about mark. It also poses a different story on how it got to mark.
I completely agree with you, Scott. Thank you for taking the time to address this situation, hopefully RUclips will take notice and improve their policies regarding copyright infringement AND the appeal process. It's a shame Mark won't get credit for all of the views his video is getting - it would probably be the number 1 electronics video of 2024 if he did. Little Tommy should be ashamed of himself and his "products". Regards, David
If manufacturer isn't ashamed of it, they should be. Those stand offs, the cable tie mounts, the case...screams home build, and not in a good way. Case design is a joke. Structure around each corner relying on one screw 😬
Even if I had that kind of outlay at my disposal, there's absolutely No Way a 'control amp' of that value would be part of my system ! Some 'audiophile's' have literally got more money than sense.
We sell vintage gear. If something we sell fails we fix it for free or, if it's been a good while, for cheap. The fact Mr Evans did not do this in the first place started his own demise. Karma my friend, Karma.
Absolutely agree with you. For that price. This kind of gear should get literally a life time warrenty. Especially if it is a part that costs 50 cents. Even the shipping should be covered. I think there is no single part in that unit (electronical one) that costs more than 10$. I hope that will be the last unit this Mr.Evans has ever sold from now on.
Sadly YT went woke a long time ago. You can see the most horrible things here, but if you comment in a way that hurts the offender in any way it gets taken down hard karen style. Truth that should be Nr1 at any time, does not matter in here if you offend...........And if i write my honest opinion, this comment will be deleted. Sad.
It is also the fault of youtube to not check if the copyright claim is legit or not.. if they did then there would of been no copyright claim... so in that regard 80% the fault of youtube !!!
I definitely agree with this point, RUclips don't actually review using people, unless someone with enough influence gets involved, and then suddenly it is fixed without explanation.
So the crux of it is that the manufacturer was butt hurt because of marks honesty so he filed a frivolous claim. I wish it was possible to take these type of cases thru court and set precedence, then file with youtube for lost revenue, or sue for it. Until there is a permanent "right of repair" laws in place these companies will continue to make "throw away" technology.
I love the fact that because of one obscure person that suddenly thinks they're important has been slapped by the full force of the internet and is now a known, shameful embarassment to the world of electronics and high end electronics buyers. FAFO has never had a greater meaning than this.
The way this issue has blown up all over the net and given the manufacturer exactly the opposite of what he was hoping to achieve may well put him out of business.........karma?
youtube are greatly annoying me .. and its growing. they are fixated on this type of activity, but take no responsibility for the false and deceptive adverts THEY insert into videos,
That preamp was not a quality piece of electronics. I suspect the manufacturer didn’t want people to see how cheap the gear is compared to what you’ve paid for.
$30,000 usd for a phono preamp that's made, entirely, with mundane/generic off the shelf parts AND it looks like a teenager's DIY kit internally? SIGN ME UP! On second thought, give me two. A white 'un & a black 'un. OOOOOOOOOOWEEEEE!!!! This is, literally, a man selling his rough prototype as the highest of high end. It's laughable. ...and what makes it even more laughable is Tom Evans thought it would be downright impossible for someone other than them to repair this phono preamp. It's so intricate and exotic that even the repair should cost about $6,500 usd. ...and then you see that it's only difficult for someone else to repair it because they've sanded the model numbers from the mundane/generic off the shelf components. The repairman who is currently dealing with the fake copyright claim not only reverse engineered a detailed schematic for the entire build of the preamp...but he located and repaired the issue EASILY! ...but, all that said, we shouldn't need an occurrence such as this to know that most (ALL) ultra high end audio is snake oil. Tom Evans REALLY should have let one of their low level employees repair that preamp for free. Now the whole world knows their product is overpriced by $29,000 usd.
IThat video is what shows that the £25,000 worth of work hasn't passed the test. It looks very similar to the first steps of an electronics beginner, so Fred must have done reverse electronics to make sense of those stacked PCBs, that's all.
Then by YT's reasoning, every car repair video out there should be struck for copyright, especially if the mechanic is calling out shoddy engineering and or build quality.
NOT a Preamp, but specifically just a Phono Preamp. Regular, Line Level Preamp not included... (It costs $30,000 U.S. because, apparently, it contains Alien tech.)
Mark did a great job. I should imagine putting together the manual and the schematics was time consuming. However, the electronic repair was really straight forward. There was a short, causing feedback. So, find which board it’s on. Once found, use an infrared temp monitor to check what is hot. Replace hot component. The physical repair was far more work along with disassembly and assembly.
My former favorite audio gear shop had all amps with the case removed in the window. You could see how it’s built before you even enter the store. You could spot the good designs from far away. Sadly the shop closed
Well said Leave Mark alone. The person who knocked up this Box of shed built garbage using other peoples circuit designs was not happy to have his shoddy and over priced work exposed for what it is.
That right there is insanity. Mark does some amazing work, as the video attests. A guy who designed this relatively basic preamp should never have bet against Mark
I know very well those little black capacitors that you can see every now and then in Mark's repair video, and they are absolutely crap, they are the cheapest ones you can find at a well-known European supplier of electronic components, and honestly seeing them installed inside a $25,000 device, made me realize what kind of scam the person who bought it got. Not to mention the choice to install tantalum capacitors, which notoriously have the tendency to completely short circuit or explode..
Tantalums are not necessarily BAD capacitors. They have relatively high capitance without having a liquid electrolyte so they don't leak like electoytics. But when they fail, they FAIL.
@marshalltjones You're absolutely right, tantalum also has its positive aspects, and in the end it still remains a choice of whoever designs the circuit. Personally, I prefer the classic (good) electrolytic capacitors, there are also some guaranteed for 10,000 hrs at 105°C, they are certainly expensive, but perhaps with a $25,000 device, they could fit 😉
I suspect it wasn't Mark's video that the manufacturer had a problem with, it was the absolute slating they got in the comments section. Mark never stated anything in his video that was anything less than factual based on what he saw while actioning the repair.
I think the only reason the video was taken down is because obviously the manufacturer doesn't want people to know how cheaply made it is. He just wants to hide the fact that it's a cheap shity amp.
If the manufacturer had quoted a sensible repair price or simply repaired it free as he ought to have done given the exorbitant purchase price then none of this would have happened. As it was, the quote indicated it would take him about 3 weeks to fix it at a sensible hourly rate.
Even the box (with its cardboard shims), the cheap looking external phono connectors, the pointless dip switches and the array of tasteless stickers make this thing look like it came from Temu.
@@G-ra-ha-m He really should use metal standoffs. But even better he should design it better. I don't see the need for 5 stacks of PCBs, I'm no audio design person but I'm pretty sure you could achieve same or even better audio performance with one big main board and one level of plug-in pcb cards of some sorts.
Although I agree with the comments on this video and multiple others highlighting this fiasco, lets not forget the appalling attitude of RUclips in this case. It is clear that they do not care about their content creators, as long as the money keeps rolling in! It doesn't take a genius to look at the facts and see that this was a "take may ball and go home" punishment hit with no real evidence of any copyright infringement.
For £25,000 UKP (not USD) I would expect installers to come to my home, work out the acoustics of my rooms, fit a home cinema system (that also plays music), and have secondary sound in other rooms, including the toilet, so if I have people watching a movie with me and someone needs to go to the loo nobody misses anything.
No popcorn needed. Either Tom Evans legal advice (unique to English Law) is correct - in which case you'll quickly hear nothing more from Rossman, or, it's not, in which case Tom will do nothing. In both case you'll also see absolutely nothing...zilch...through your popcorn ;)
In my opinion, the manufacturer of that pre-amp needs a very hard kick in the arse for their nonsense. Copyright for a repair video. Seriously? They need to get a life!! Sure, those tantalums are expensive, but in no way does their cost justify the 25,000 pound price tag. That's brand new car money here in Australia.
I remember watching that video before it was taken down. That preamp was hideous. I wouldn't have paid $25 for it, much less $25,000. But then again, that's the "audiophile" market. Lots of fakes out there.
It looks like a Preamplifier I built when I was 14 years old, 47 Years ago from an ETI Kit. All of those Components could have been placed on 2 Main Boards in a proper Silk Screened Case.
Total apoyo a Mend It Mark. Todo el problema es que ha la marca le molesto que Mend It Mark lograra esa reparación aun cuando ellos lo retaron diciendo que no podría, vivimos en un mundo que compras un equipo o vehículo y no puedes hacer lo que quieras con el, tienes que pedir permiso al fabricante, una total locura, si pagas por ese equipo es tuyo no del fabricante, el propietario puede hacer lo que le de la gana, el mundo al revés y no apoyo eso para nada....
i loved Mark's video. I used to know a bit about electronics but less these days. I have to agree that the build quality of that preamp would be questioned by me if it was £250 never mind £25,000
If there is any concern about environmental destruction, there should be law requirements that at schematics and component lists should be aviable for all electronic gear sold. There is so much electronic stuff that would be super easy to repair with schematics that are filling up landfills.
Having worked as an A/V tech since the eary 70's i have seen a lot of gear to repair and these so called Hiegh End ones might look the part on the outside, but inside they simply don't justify the asking price. This is what Mark showed us, there was zero copyright on anything, yet RUclips accepted the compalainants word and placed a strike against Mark for no good reason. If this trend continues then repair videos will become too risky. Now this video has gone viral, yet yo my knowledge none have been taken down. RUclips and Tom Evans owe Mark an apology.
I believe they were objecting to the very nice, professional, reverse engineered schematics which Mark had made and shown publicly. However, AFAIK, it is not a breach of copyright to publish schematics after reverse engineering some one else's design as long as they are your own schematics or you have permission to publish their schematics. If it was a novel design, it could be patented, but that would only prevent it from being made and sold by someone else. The price charged is irrelevant. If someone was willing to pay that kind of money for that low-noise performance, then they can (as long as it performs according to spec.).
@@Arek_R. I can't actually fault him for that. Connectors are great for ease of assembly and maintenance, but in a high-end analog audio application that's not expected to be moved or serviced often, I'd actually prefer point-to-point. Connectors can introduce noise and will always come with a small degree of contact resistance. Having said that, I couldn't say for sure it'd make much difference here, and besides, there are SO many other aspects of the design that could use some more thought... 😀
It would be good if we could get the facts straight. It retails for £25,000 _not_ $25,000. This was stated incorrectly at the start of the video, but got corrected by 6 minutes in.
@TheDefpom Fair enough. It was a snotty comment by me. Louis Rossman kept getting the numbers wrong in his first video, so I was kind of triggered by it. Thank you for the video, though. I should have said that first.
I agree, in my recent video about the content of Mark's video, I came to the conclusion that there was nothing copyrightable have hence the copyright takedown request is invalid. Functional block diagrams are functional and inherently not subject to copyright, showing the circuit board is also functional. Marks drawing circuit diagrams, or showing the standard op amp recommended circuit diagram is also not copyrightable.
Well done, Mate. I respect your opinion towards Mark. He is a great engineer in his own right. I’ve been repairing electronics since 1978, especially tube/valve amps and etc. your videos are really informative and interesting. And a big shoutout for Mark…..!
This is what happens when you allow or use platforms that are controlled but with everything it can be used for something to go against someone unfairly without a way of evidence the claim was made in the right way.
IMHO, I don't consider tantalum bead capacitors as ''quality'' components. I've had nothing but trouble with them over the decades of repairing stuff, they often show the correct value for capacitance, but are faulty, and I certainly wouldn't put them in a PSU. I'd only use tantalum bead if physical space or leakage were a problem, like in a timing circuit. For a quality PSU, I'd just parallel several good quality, 105 Deg C electrolytics, with a couple of 100nF, plastic film or ceramics to gild the lilly.
D'you mean the old tantalum bead electrolytics, or these new non-electrolytic things? I've got a test kit with non-electrolytic tantalum beads (its only in a Chinese test kit, so I'm not too fussed, but might replace (whilst I'm still building it) If theyre bad news :)
@ tantalum caps respond faster than electrolytic, they are used when better high frequency noise filtering is needed, ideally you use both types of capacitor, and a few different values as they respond to different frequencies and help filter more effectively.
Please don't insult hobbyists. This thing looks worse than stuff I made when I was a teenager with 1-2 years of PCB design experience and I still used PCB connectors to hook up wires. This guy just straight up soldered the wires directly, in a chain that forms some sort of PCB-wire snake, Mark really struggled to work with it.
Thank you for bringing attention to this. I sometimes worry this will happen to me. Or a lawsuit. I show repair of biotech equipment. The companies that make the stuff I work on are multimillion/billion dollar companies. They also go to great lengths to prevent customer repair of their equipment. And this equipment is sometimes priced at $100k or more (with service contracts attached not much less). Yet I'm not violating copyright laws either. I'm not sharing IP. And while I worry, I do welcome the day this happens at the same time. Because the biotech industry seems to fly under the right to repair radar. Perhaps an event like this would help bring awareness to them.

Although I agree with the comments on this video and multiple others highlighting this fiasco, lets not forget the appalling attitude of RUclips in this case. It is clear that they do not care about their content creators, as long as the money keeps rolling in! It doesn't take a genius to look at the facts and see that this was a "take may ball and go home" punishment hit with no real evidence of any copyright infringement.
Wow. This certainly backfired on the manufacturer.
It is also being shared in many many audiophile groups too. The damage to the Tom Evans audio company is immeasurable..
yeah but meanwhile tho, he at least sold 58 of those devices for 25k a pop.. do the math, he made alot of money with this crap.
@@whoknows8225wonder how many are now sitting in the warehouse?
Thxs for the video and your support!
For £25,000 UKP (not USD) I would expect installers to come to my home, work out the acoustics of my rooms, fit a home cinema system (that also plays music), and have secondary sound in other rooms, including the toilet, so if I have people watching a movie with me and someone needs to go to the loo nobody misses anything.
That would be quite good value for that much work.
Supporting Mark. Dislike the manufacturer
I'd like to know the fool who packaged this pile of rubble in the first place. If it's worth so much, how can it be so shoddily packed.
Here is to Mark and Louis. Popcorn at the ready.
No popcorn needed. Either Tom Evans legal advice (unique to English Law) is correct - in which case you'll quickly hear nothing more from Rossman, or, it's not, in which case Tom will do nothing. In both case you'll also see absolutely nothing...zilch...through your popcorn ;)
In my opinion, the manufacturer of that pre-amp needs a very hard kick in the arse for their nonsense. Copyright for a repair video. Seriously? They need to get a life!! Sure, those tantalums are expensive, but in no way does their cost justify the 25,000 pound price tag. That's brand new car money here in Australia.
In England luckily the EV movement has made the average car cost over £40k now, so it's about the cist of a new battery pack... !
In my opinion, it's mostly RUclips that just completely stopped caring about their content creators 😞
I remember watching that video before it was taken down. That preamp was hideous. I wouldn't have paid $25 for it, much less $25,000. But then again, that's the "audiophile" market. Lots of fakes out there.
With every post..an angel gets it's wings. Our friend thanks you, lad :)
A preamp without shield cables. What is that?, A piece of crap. I do better things when i was engineering student without experience.
The manufacturer sent it to him for repairs 😮
Mark is a top rate and talented engineer ❤
that's the irony of it 🙂 Mark deserves all the support of the world. such a lovely and super competent person!
The pre amp, is a scolar proyect, & no more 400U$D materials
I think RUclips copyright attorneys have no idea what copyright law is all about. IMO there's nothing copyrightable in that video.
Apparently they will take the word of the person making the claim every time, and the target of the claim has to prove innocence.
@@richardgray8593 That's how the judicial system works now...
right on -- its all about the poor build quality and high price
It looks like a Preamplifier I built when I was 14 years old, 47 Years ago from an ETI Kit.
All of those Components could have been placed on 2 Main Boards in a proper Silk Screened Case.
Hey I remember them built a few kits. Great days saving up to get a kit.
Total apoyo a Mend It Mark. Todo el problema es que ha la marca le molesto que Mend It Mark lograra esa reparación aun cuando ellos lo retaron diciendo que no podría, vivimos en un mundo que compras un equipo o vehículo y no puedes hacer lo que quieras con el, tienes que pedir permiso al fabricante, una total locura, si pagas por ese equipo es tuyo no del fabricante, el propietario puede hacer lo que le de la gana, el mundo al revés y no apoyo eso para nada....
i loved Mark's video. I used to know a bit about electronics but less these days. I have to agree that the build quality of that preamp would be questioned by me if it was £250 never mind £25,000
Or even just £2.50
Having judged and mentored many B.S.E.E senior projects, I would be horrified if this design was submitted.
If there is any concern about environmental destruction, there should be law requirements that at schematics and component lists should be aviable for all electronic gear sold. There is so much electronic stuff that would be super easy to repair with schematics that are filling up landfills.
Couldn’t agree more.
Yes, another reason to support "Right to Repair" laws.
Having worked as an A/V tech since the eary 70's i have seen a lot of gear to repair
and these so called Hiegh End ones might look the part on the outside, but inside
they simply don't justify the asking price.
This is what Mark showed us, there was zero copyright on anything, yet RUclips
accepted the compalainants word and placed a strike against Mark for no good reason.
If this trend continues then repair videos will become too risky.
Now this video has gone viral, yet yo my knowledge none have been taken down.
RUclips and Tom Evans owe Mark an apology.
Congrats for your video and I agree totally with you.
I believe they were objecting to the very nice, professional, reverse engineered schematics which Mark had made and shown publicly. However, AFAIK, it is not a breach of copyright to publish schematics after reverse engineering some one else's design as long as they are your own schematics or you have permission to publish their schematics. If it was a novel design, it could be patented, but that would only prevent it from being made and sold by someone else. The price charged is irrelevant. If someone was willing to pay that kind of money for that low-noise performance, then they can (as long as it performs according to spec.).
I think You nailed it pretty good there.
Louis Rossmann has also posted the original video on his YT channel. He's encouraging ME to try and get it taken down. Louis will fight.
A nightmare to service because the way they the circuit boards are stacked
Not a single wire-to-board connector.
I design my stuff I even like to slap connectors everywhere.
@@Arek_R. I can't actually fault him for that. Connectors are great for ease of assembly and maintenance, but in a high-end analog audio application that's not expected to be moved or serviced often, I'd actually prefer point-to-point. Connectors can introduce noise and will always come with a small degree of contact resistance. Having said that, I couldn't say for sure it'd make much difference here, and besides, there are SO many other aspects of the design that could use some more thought... 😀
It would be good if we could get the facts straight. It retails for £25,000 _not_ $25,000. This was stated incorrectly at the start of the video, but got corrected by 6 minutes in.
@@dizwell I live in a country that uses $ so I said it without thinking, and then didn’t notice I got it wrong in the edit.
@TheDefpom Fair enough. It was a snotty comment by me. Louis Rossman kept getting the numbers wrong in his first video, so I was kind of triggered by it. Thank you for the video, though. I should have said that first.
I agree, in my recent video about the content of Mark's video, I came to the conclusion that there was nothing copyrightable have hence the copyright takedown request is invalid. Functional block diagrams are functional and inherently not subject to copyright, showing the circuit board is also functional. Marks drawing circuit diagrams, or showing the standard op amp recommended circuit diagram is also not copyrightable.
YT needs to remember what happened when MySpace was king of the internet.
Well done, Mate. I respect your opinion towards Mark. He is a great engineer in his own right. I’ve been repairing electronics since 1978, especially tube/valve amps and etc. your videos are really informative and interesting. And a big shoutout for Mark…..!
Cool to cover it 🆙🆙 also re-upload it. I wish that the manufacturer would come out and say sorry and go into a positive discussion.
Mend it mark is great. 👍👍👍👍
They always leave Marks workshop better than they leave the factory anyway 👍,cant speak for the mail companies though !
Thanks for covering this.
This is what happens when you allow or use platforms that are controlled but with everything it can be used for something to go against someone unfairly without a way of evidence the claim was made in the right way.
IMHO, I don't consider tantalum bead capacitors as ''quality'' components. I've had nothing but trouble with them over the decades of repairing stuff, they often show the correct value for capacitance, but are faulty, and I certainly wouldn't put them in a PSU. I'd only use tantalum bead if physical space or leakage were a problem, like in a timing circuit.
For a quality PSU, I'd just parallel several good quality, 105 Deg C electrolytics, with a couple of 100nF, plastic film or ceramics to gild the lilly.
D'you mean the old tantalum bead electrolytics, or these new non-electrolytic things?
I've got a test kit with non-electrolytic tantalum beads (its only in a Chinese test kit, so I'm not too fussed, but might replace (whilst I'm still building it) If theyre bad news :)
@ tantalum caps respond faster than electrolytic, they are used when better high frequency noise filtering is needed, ideally you use both types of capacitor, and a few different values as they respond to different frequencies and help filter more effectively.
The build quality is terrible. This thing looks like it was made by a hobbyist, not a 25k device.
Yes it was made in a garden shed.😂😂😂😂and if it was not sure like hell it does.
Please don't insult hobbyists.
This thing looks worse than stuff I made when I was a teenager with 1-2 years of PCB design experience and I still used PCB connectors to hook up wires.
This guy just straight up soldered the wires directly, in a chain that forms some sort of PCB-wire snake, Mark really struggled to work with it.
I watched the original repair video & have to agree about the build quality, only a stinking rich audiophool would pay 25k for such an item!
a Fool and his money, is easily parted.... 25k for that? fk the rich
Thanks for your support to Mark's experience 🙂❤ new sub indeed 👍
Thank you for bringing attention to this. I sometimes worry this will happen to me. Or a lawsuit. I show repair of biotech equipment. The companies that make the stuff I work on are multimillion/billion dollar companies. They also go to great lengths to prevent customer repair of their equipment. And this equipment is sometimes priced at $100k or more (with service contracts attached not much less). Yet I'm not violating copyright laws either. I'm not sharing IP. And while I worry, I do welcome the day this happens at the same time. Because the biotech industry seems to fly under the right to repair radar. Perhaps an event like this would help bring awareness to them.
