Pointed out on the American forum.

The two links below are a before & after examples of compound, shear stupidity. It is also a lesson in why you replace tired Electrolytic caps & don't power things that have them and have been sitting unused, for who knows how long.

This character has absolutely no idea: Checking Ecaps with an Ohm meter??? Beggars belief.

Newbies should watch this to see what often happens when you fail to heed the warnings & power an unknown set without basic checks to see if it is safe to do so. Most times its not and it will need work before it is safe. Safe applies to the set as well, things like valves, as you will see, can get destroyed, doing the wrong thing.

This really should be removed: There are plenty more examples of idiots demonstrating their ignorance on the WEB: These are dangerous people.

There I was expecting to see a multi-section cap launch itself through the guy's roof.

What a goose! And he calls himself Super-Genius.

(BTW: That second link above doesn't relate to the first one.)

I like how he looks at the power plug, all but declares it a write-off (and it is), then goes ahead and plugs in the CRO without testing anything. He was off to a bad start the minute he put it on his workbench.

As for the music video, it reminds me of the TV programme Solid Gold from the 1980s. He can play the guitar quite well.

There was so many times where this guy fails....

Too many to list.

This is the best video example of what not to do.

Valve radios, They just don't make them like they used to

A classic case of a little bit of knowledge is dangerous.
In this case very little knowledge and possibly a good test for would be electronic engineers to spot how many errors he makes.

The valve arcing the way that one did isn't likely to pop a 3 amp fuse, particularly one feeding the primary transformer winding - possible, just not probable. This one is a definite test and repair before power up. There'll be faults he hasn't even thought of yet. First, even before considering that this is a kit assembled by a hobbyist, is disconnect all leads from the transformer and Megger all windings for continuity and insulation. If that passes, replace the whole power cord with a double-insulated one and a new plug top and then go from there with the testing regime we place on our radios.

Before he even starts this I'd recommend he do some reading. Everything is rush rush, just so it can be filmed and his workshop is a pig sty. The work space should have nothing on it apart from the item to repair and any necessary test equipment and spare parts and boxes of valves shouldn't be occupying the space his stool should be in.

I have replaced these with a direct cut & paste from the American forum.

The UPS has been working overtime as we had a line of thunderstorms last night & they continue.

These should work Nr two is dumber than the first.

As one on the other forum pointed out: In front is a big black "Bumblebee" cap. Those are like Waxed Paper, Oil filled & Micamold: Replace, or at minimum test on sight.

The only way to leakage test a HV cap is with HV, I have an insulation tester for that as well as a couple of other devices. That can test them at close to their rated voltage.

I do love the 3K quoted for a cap. You cannot test an electrolytic that way (with an ohm meter), its meaningless. As is trying to test that lot in circuit.

You can at LV or on a bridge, have the cap test the right value. I tossed a Plate bypass cap that I could not believe was left in whilst others were replaced? That is the most likely NP to fail in a valve radio. It HV tested 3K & 250VDC, now why was the set not working?

Possibly listening to this clown.

Below is a link to the original post. That is a revelation in itself as to age & gender of the person ( Disclaimer: That age & gender comment, is taken from the other forum: Not mine, or this forums opinions)

I was amused as the 6X4 gave the classic symptoms of a short on its output for a while, before blowing itself up while he waffled on. Luckily the transformer was saved by the fuse going.

Then he picks up what looks like a 12BH7 or 6CG7 and considers it as a replacement... or perhaps using a few transistors. Good luck with that.

Then the replacement 6X4 also starts glowing blue, luckily at that moment he happened to decide to switch off. What a moron.

In another video he says he's not an electronics person and not that interested in it. So what's he doing fiddling with stuff he clearly knows nothing about? Sooner or later he's going to remove himself from the gene pool.

I'm on my way home from the Fest. In Holbrook eating some grub at the moment. I drove through all that rain.

Comments were made re gene pool on the American forum & I was one of them contributing.

That comes under "Darwin awards" Honouring Charles Darwin, not denigrating, him or his work: More about survival of the fittest.

The gong is given to the idiot that manages to wipe him / her self out in the most spectacular fashion doing the stupidest thing imaginable; preferably before breeding & contaminating the gene pool by producing another in the same ilk as them.

It is an extension of the theory that accidents were designed to purify the species, by eliminating the genes of those who engaged in extremely stupid & dangerous pursuits.

I placed a comment on YouTube. I've taken a screenshot and will post it here if he deletes it. That video reminds me of an episode of Russell Coight.

That poor oscilloscope, that was hard to watch! All the gear and no Idea... Very sad indeed. I would love a piece of equipment like that, at least Coight was sort of funny, that was really tragic, he should have everything confiscated and given to somebody with respect for the stuff. Some of the comments are equally disturbing! Ughh.
Why, just why, be such an ignoramus when there are so many instructive resources available, including this site, where correct procedures are promoted?? It Beggars belief. I've made some stupid mistakes admittedly, but admitting it is one thing, but putting it on you tube and acting like that is beyond ridiculous. Embarrassing to even watch! Vandalism!

Luckily the transformer was saved by the fuse going.

But in attempt number 2, he replaces the "3 watt" fuse with a piece of wire.

Have to say the videos were the most painful ones of stupidity I have seen in many a long day. Love replacing the fuse with a piece of wire and there are so many things done wrong I lost count.

The guy is a complete idiot and that is being polite. Totally has not a clue what he is doing and one wonders what his motives are in producing videos in the first place ??

The videos should be taken off YouTube.

Embarrassing to see.
