Dartzeel amp schematic - build this?

So all that is needed is an original PCB and an X-ray machine, then?
(to follow traces in a multilayer card)
Shall we simply buy original 458 together. Peanuts: just about €10.000 each of us. You can keep left channel and I take right channel and start digging into the subject. 😀

Seriously now: let's keep our NHB-108, listen to fine music and wait until Chinese do the job. 🙂
 
It is not crazy, it is creativity, courage, determination...

As usual: "All You Need is Money"

The Chinese who cloned NHB-108 really purchased it, dissassembled it and made a clone which we use now.
HERE is the original thread where the "prototype" NHB-108 was unboxed, somewhere in China. Below is a photo of the "prototype before the unboxing.

In post #7 on that thread somebody said "Do it as usual, dismantle it completely, then copy the board ~" and they did it. Awesome. That's a real "DIYers spirit", not simulation. 😀

Therefore this "single pair" Dartzeel NHB-108 isn't just a copy but a real 1:1 clone. All we have to do is to get a pair of bare boards, assemble it from good components, add a quality power-supply and make a decent chassis. This clone is not a poor-mans amplifier but has potential to be improoved clone in a decently designed chassis. To my taste, the original chassis is outright uggly. 😱

I. e. $170.000/50=$3.400 per person..
hmm


That is just silly. Why on earth would you need two?

Besides, as we know, there is a cool down period for anything you buy in the EU. Is two weeks of peeking under the hood not enough? Provided you don't leave ugly tool marks with your wrench set, there should be a full refund minus the shpping coming back. So, how about $10 per person? 😛

Wow, that IS a great idea 🙂
The Law is the Law!
But, really, would it even be possible to reverse engineer the card without X-raying it?

Chinese are crooks
 
Another option is to ask "the Russians" to hack a certain server 🙂
(like Candidate Trump mused about during the election process regarding the Clinton mailserver)
No way, the main hacker is on cold in London Tower waiting for execution ... I mean extradition. But whom should he be extradited if the crooked cop was fired because he was a Comey... I mean a Commie.

Sory for typos, but I guess you know what I mean.
 
Does that mean many of us on this forum are aspiring crooks, as well?

Another way of looking at this issue is calling it Democratization: Enabling scores of people not part of the 1% to buy otherwise ridiculously Overprized stuff...
But Hattori, please.

adason has a delicate sense of humor but has forgotten to insert several smileys for those who do not understand the joke. 🙂

He also is a proud owner of Chinese clone and seems to like it.:violin::geezer::spin:
 
Did y'all see this Hungarian 458 schematic diagram? The last one in the Hungarian thread, but still no comments there.
At least it has got 2x4 output transistors, just like the 458.
Who is to say that this is not the real deal?
