Can you open up a D2030 (triangle) and take photos, so we can see what is inside, and our opinion about it can be more informed?
IF at all possible, it would be interesting to see the chip sold as TDA2030 and 2050 size differences.
No compromise, of course.

I received an email from Dan/ akitika.com with some info about NTE7197,

Looks like nte7197 is actually an lm3886 authentic TI chip.

The NTE7197 will be an authentic LM3886 until NTE’s supply of them runs out, then they will buy whatever fakes they can get.

This site tells me NTE has 29 employees, and is based in NJ, established 1979.
The company claims 40,000 square feet warehouse space, and 98% order fulfillment in 24 hours.
They also sell electrical parts.
So it is a good source for North American customers.
Also, it seems to be a trading company rather than a manufacturer, getting parts made in their own markings from different suppliers to their specifications, apart from commonly traded items.
Quality, I have no idea, as I have not needed to deal with them.
I may have looked at the wrong NTE...

I think NTE ran out before TI did, that was long back in this thread, unless they got replenished.
May not have them in stock.
It is also remarkable that the Chinese and Taiwanese are not making copies of the 3886, they do seem capable enough to do so.
Seeing Vipin's posts above, there are copies of copies in China, so what prevents them from making copies of the 3886 is something I cannot understand.
Or they exist, but not yet well known.

Chinese made copies of copies, and as for usefulness they also copied 3886 , it's will be unpleasant to get them in the name of Original
Chinese also copied UTC/Taiwanese licenced products too,
Hello guys
Little bit off the Subject here
I got some capacitors recently
ELNA RJ4 Series 105°C Capacitors
What you think about their Originality and Quality
Capacitance is within 8%
ESR is 0.06 , Datasheet says that 0.13
Here is the link for video

True enough, but having 4 of them, all 4 sides can be shown in a single picture 😉
Geometry 101 😉
On the other side we are missing a good closeup of the rubber seal, which certainly can tell its side of the story 😱
In any case, we are only seeing "a plastic sleeve"
FWIW it is EASY to cut open an original one, flatten it (maybe between 2 glass sheets), take a picture of any resolution needed, "clean" image in Photoshop or even redraw it in Corel Draw which admits bitmap input and turn it into a perfect Vector image.
Output in 2 bit Black and White is the perfect artwork to have tens of thousands printed and used to wrap junk, if so needed.
Meaning: I don´t care too much about "Forum picture identification", a dedicated faker can copy that easily.
If anything, "mechanical" stuff , such as transistor or IC back metal parts are much more difficult, they involve expensive dies and machines.
But .... a LABEL? .... any day of the week..

The dies on top (vents), and bottom (seals) are hard to make, and distinctive, like the tabs on different 2050 like shown previously.
There are web sites about those, and experienced people can identify capacitorss without the sleeves.
Check out Mouser etc., 105 degree caps are less numerous than 85 degree ones.

FWIW, the dents on top look genuine.

Woah!! Independent thought. Crazy!! Don't go start a trend now... 🙂
True that. Apparently some fakers are buying/scavenging test rejects of legit ICs and packaging them. If you have a source of the dice, you're golden. The wire bonding and packaging equipment is more manageable to get ahold of. It'd take more than a garage faking operation, though.
