Streisand Effect in action! :)

[@fredfred2363]

Oh yes. 👍🏻

[@Chris_Grossman]

Even if the Tom Evans preamp was worth the ridiculously high price he charges one should avoid buying anything from him for his attempt to silence Mend It Mark. Many people have reposted Mend It Marks excellent video. All Tom Evans’ attempt to suppress it did is bring himself more bad publicity than he ever would have received from doing nothing. Tom Evans must not have heard of the Streisand effect.

[@TheBaldOne]

This had nothing to do with copyright, this has everything to do with someone that was clearly pissed off for being called out passively (and with reason I might add) for selling cheap hardware at overinflated prices. In the video we can see Mark making several remarks at the build quality, which is a far cry from the price charged, and that sent Tom Evans over the edge and the only way he had was to issue a misleading copyright claim that now blew up in his face. Mark's skills in reverse engineering the amp are nothing less than extraordinary and the quality of it is amazing, he drew the diagrams just by looking at the boards and understanding how it works. Tom Evans should've eaten humble pie and kept quiet, instead he chose to put a spotlight on it. Someone is not familiar with the Streisand effect.

[@IanScottJohnston]

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!

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.

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 KZbin 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. KZbin and Tom Evans owe Mark an apology.

[@muhdiversity7409]

[@davidewhite69]

[@randalltufts3321]

So the crux of it is that the manufacturer was butt hurt because of marks honesty so he filed a frivolous claim.

Until there is a permanent "right of repair" laws in place these companies will continue to make "throw away" technology.

[@christopherguy1217]

In my opinion you can't trust a manufacturer like this Tom Evans that tries to hide videos exposing their products and that spends the time to sand off the markings on the components. You see this from all the cheap dishonest Chinese manufacturers that a company which sells a pre-amp for £25,000 just shows you what kind of company they are.

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.

[@mattb9664]

Despite potentially having clean pre-amp performance, that Tom Evan's preamp is still a piece of garbage from a mechanical standpoint. You don't just take a bunch of your breadboard building blocks then gang them together in an acrylic box. Using plastic stand-off risers to secure everything. This incident somewhat exposes how much of a scam still exists in high end, audio electronics. These people take advantage of the more affluent, wealthy people with promise of having some type of a luxury listening experience, with unique 'looking' equipment - which is all mostly BS. Once you spend a certain amount of money, the improvements get into diminishing return- period. Supposedly 'bespoke' and made to order, one-off equipment. Hopefully this is a lesson to those that can afford this equipment - and how much of a scam it can be!

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.

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.

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.).

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.

[@petegaslondon]

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.
