YAMAHA's Professional Amp

UPDATE: So I’m running a 3-part LIVE workshop that takes us on… A Time Travel Through Vintage Electronics. We’ll rewind the clock, dive into the tech of the times… (and study the very history of how things were broken and repaired has evolved) The workshop is coming soon, but if you're reading this then you're in luck (or not)... And there's still time for you to sign up using the link below: www.menditmark.com/mend-mark-workshop The workshop dates are mentioned in the link above too.

Is there anything that you don't look forward to more than a new Mark video? Keep them coming please!! Also, it would be great to hear how you gained your knowledge. Electronics, chemical, mechanical, you know it all!

I recognise that amp as one from Birmingham Repotory theatre. It came into where I was working at hte time for service. The initials JD belonged to John Deakin one of the service technicians. A long time ago in the seventies. He has since passed away sadly.

Let's get this man some more subscribers. There are a lot of channels that are really crap that have more subscribers than he does. Mark is the real deal when it comes to repairing electronics! This man takes so much time and effort in putting these videos together. In such great detail, next to nothing skills and when something is not available, he makes it himself. Mark is such a nice guy, great knowledge and very entertaining to watch. Every time he puts out a new video like this, you can take your popcorn and drinks and watch this from start to end like you watch a new episode from your favorite series. Keep up the good work Mark, great to hear you move to a new workshop.

Fabricating those transistor covers is just next-level refurb; not only painting, but matching the text. Awesome.

Dare I say that Mark's videos are on the edge of being therapeutic to watch! Thanks so much, Mark!

Mark exudes confidence and competence. You know he’ll sort this disaster

No surface mount items, no chips...ah the joy of components that can be examined, tested and replaced without magnification!

Mark shows us a level of craftsmanship that many ‘repair shops’ don't even know exists.

The sticky residue on the cables is from the smoke, not dry ice 😁 . The smoke fluid is water and glycol, and the glycol is the thing making the smoke white. If the smoke is used in a nightclub without any ventilation, the glycol will condense on stuff. A typical fault on movingheads is the condensed glycol on the cables inside, making the dust stick on them, and making them brittle.

Mark is one of my favorite net personalities. Straightforward with no mucking about. Can't wait to see the new digs.

This is more than just mending. To see someone taking care to recreate missing parts from raw steel is truly a labor of love.

You won’t find anyone as professional as Mark he’s the best !

Can we all admire what appears to be masking tape with “nope!” written on it :D

I bet if you sent Mark a shoebox and told him it was a McIntosh amp, you’d get a McIntosh amp back in 10 business days 😂

The abject anxiety I get watching Mark completely dismantle these old buggers is offset by the dopamine blast I get when it comes back together and actually works.

A great end to a hot and sunny weekend. I like the way Mark goes the extra mile to ensure that all repairs leave in a safe condition. Best of luck moving to your new workshop.

Genuine shock when Mark said he'll be moving shops, I thought he loved the clutter! Extremely organized, however the lack of space is only somewhat evident(;

It's better to watch you working than to watch a Hollywood action movie. Lots of love and regards from Pakistan. Stay blessed.

Good afternoon Mark! I can relax, cuppa tea, and watch your great video!
