Tom Evans Audio copyright strike

Upload

In November 2024, YouTube creator Mend It Mark uploaded a video in which he repaired a MasterGroove SR Mk3 pre-amp made by Tom Evans Audio. In the video, he took the pre-amp apart and to help diagnose the issue, he reverse engineered the device and created some schematic diagrams. He also made his viewers aware of the fact that the price of this pre-amp is £25,000 (about 30,000 USD) and that many of the electrical components in the pre-amp had the part numbers scraped off.

After upload

After the video was published, Tom Evans Audio issued a copyright strike against the video which resulted in the video being taken down. Mend It Mark was not informed on what the copyright infringement was. This decision was met with criticism from creators on YouTube since it questions whether or not showing a circuit design in a video could be considered copyright infringement. In December 2024, Louis Rossmann re-uploaded Mend It Mark's original video to his channel with his own introduction. As of January 2025, the video is still up on his channel.
