“The biggest question is what exactly was copyrighted in the original video, which was tough because YouTube refused to pass on [Mark]’s questions or provide further details.”
Tom Evans sent a broken £25,000 pre-amp to Mend it Mark as a repair challenge. The fault was one bad tantalum capacitor, and the insides were carefully matched op-amps with no special circuitry. Then Evans filed a copyright claim and YouTube pulled the video. Showing customers what £25,000 buys is apparently the one thing the manufacturer can’t allow.
