Mend it Mark takedown.

[Mike Watterson]

but again, let's be mindful in what we say here.

That's fair. Actually I'd not checked and wrongly assumed this was in the Members Only bit.

I saw (caught!) the original video, plastic case, unscreened wires (the list goes on). Mark is an entertaining and clever fellow with a workshop(s) to be envious of, I like the way he seamlessly transfers from electronics to mechanics. As to copywrite infringement by definition this thing was in the public domain i.e. you can get one. It's yours to do with what you like. Did the sale have a license agreement like some software has?

What is particularly interesting is that Mend it Mark was not supplied with the schematic for the phono stage he fixed. He worked out the schematic himself - it is a peculiarity the he can in fact claim copyright for his own service manual and associated reverse engineered schematics.

Apparently there's no such thing as bad advertising.

After all how many audiophools look at sites such as this and the many others that are commenting.

Louis Rossmann has done a follow-up:

With Mark's blessing, he will re-post the original video on his channel.

I loved the original video but Mr Rossman's follow up is also excellent, especially the last minute.
The repair was well handled. I don't have a thermal camera, so I tend to use a cheap secondhand "fault locator" (eg low-ohmmeter) with a tone that follows the resitance reading. Hy-trak or Toneohm.
A particular hate is all those tantalums on 1970s Tek modular testgear (5000/5000 series) that fail short, sometimes after a roman candle display of shooting fire from the top! You just follow the +ve and negative rails with the fault locator and listen for the highest squeak to locate the shorted component.

Looking on the bright side (as ever), at least the manufacturer followed Les Lawry John's advice & avoided blue tants.

The original video has been uploaded to many sites and many You Tubers have added it to their site, its gone viral.
Louis Rossmann has taken up the cause and made a challenge to the manufacturer on line.

The Streisand Effect par excellence.

Rossman's repost of the video with a pre-spiel by Rossman.

Without any comment regarding Rossman or Mend it Mark's video, or the product design, I did notice that the CE mark on the rear panel does not conform to the CE definition https://cemarking.net/affixing-ce-marking/ . In any event, equipment of this kind has to pass two main tests; Electromagnetic Compatibility (conducted and radiated), and the Low Voltage Directive (mains creepage and clearance etc). Now you can self-certify if you have carried out those tests yourself and hold documentation for those tests. After that you can affix a correctly proportioned CE mark.

Self-certification explained https://cemarking.net/ce-marking-knowled...themselves.

However, I've personally used a test house, first to do a pre-compliance test to indicate if a design will pass EMC and LVD tests, or which areas need attention before a full test. Sure it costs a few grand, but you can then CE mark the product with confidence.
