Kids; try THIS at home . . .

572B Breadboard Linear Amplifier - YouTube

Of course, I would be VERY CAUTIOUS about doing this - the way this guy did it @ home.

Like that HV power transformer he used!!!

He also used a bunch of parts from microwave ovens.
So he recycled too.

Nice job, Bob / KD5MHQ.

That's not just scary it is FREAKING SCARY. Man, the HV and RF around that is wild. I'll pass. I have breadboarded some stuff in the past as a proof of concept sort of thing but I would NEVER do something like that.

I would hate to be drunk around that thing.

He's a young Thomas Edison.

It's still impressive what a guy can build with such tiny little hands.

C.K. Ive thought about it aswell and decided between the kids a child traffic and pets in my homestead NOT A GOOD IDEA!!

Now, if he were to get another very small/old microwave oven, gut it, take off its front, put a piece of 1/8" thickness of sheet metal aluminum on it for the adjustment/meter/switches/MFJ tuner, cut a large square off of the top, put some screen on it from the inside, and then mount all of that amp in it (except for the xformers and voltage supply circuit in another box) - he would be doing it right. Establish a decent chassis ground and add RF bypass caps to 'put a bow on it'.

With that much HV/current available; he could put another two 572's in it (making it four) and turn it into a cool KW amp!

But yeah; I would NOT do it like that.
Got to give him credit for being cleaver and resourceful - though.
Cannot believe he was handling those HV wires as he did; that part just freaked me out!!!

That's what I meant by tiny little hands. That calculator would make Shaq look like he has small hands.

I'll never be able to look at a bowl of spaghetti the same way again...

 

[ExitThirteen]

Not only does he use it for linear amplification... it also doubles as a bug zapper! Bet he doesn't have any flies in his house.

You could not pay me to go in that room. Thats all I got to say about that
