Hello Erikovsky
She
🙂
He is a "She", and thank you for your rely, I know and I get your point; nevertheless, please read my last statement, that may explain what you have seen.
erikovsky, if you believe that Pras1170 is the person who sold you fake SITs, don't buy from him/her again. It's as simple as that. OTOH, there are others here who've developed a good relationship with this seller.
You've made your claim, now readers are free to decide for themselves its validity. Without any evidence to support this claim I think it's time to move on instead of continuing to repeat yourself.

Hello erikovsky,
If problem is that some sellers from China sell fake parts to their fellow citizens and export real ones to diyaudio members, what is the purpose of discussing here internal chinese market issue?
To be clear, I do not support your claim that pras1170 is selling counterfeit goods.

Don't change my original message in the quote OK ?
Discovered in September 2018 this shop has only 4 feedbacks, look today is plenty of good ones.
Big respect
🙂 for Pras1170
Please write more about your SIT's tests and show us this transistors photos..
Accusate people without verification is not a truth.

1. From the beginning, I've said I will prove. Since this is a big engineering, it take times and serious thoughts.
2. If you get good SIT, why discuss here? Cuz westerners get their sugar while making everything into a "blood-diamond" cycle. You are supporting Chinese faking industry stronger while you enjoy the benefit. That is my point.
3. To Soundhappy, sometimes people delete long quote to emphasize the key words. I think this common and I suppose I am not the first one doing this?
4. To Soundhappy, "Accusate"is not English, OK?
That's it. Wait for my report, and don't be hostile to me, unless you just care about yourself.

1. So Your SIT's tests were not made today or in the past....You need time.
2. Thread share genuine transistors sellers links and try to avoid counterfeit market. The same logic for all around the world.
3. Delete long quote are normal, but transform my original message are not.
4. Accusations without proof, You understand the point ?
What if Your SIT's device under test technique was wrong connected and You panic for nothing ??
My best wishes of the genuine semiconductors 😀

Hello, I can't find your information
Please send me your email address privately (to avoid your privacy)
Every friend who buys a triode will send an email in my mailbox
So what is your mailbox?
Then, did you buy the transistor from me?
Is the package you received received from me?
If it's a package from China, you can publish the information, the seller's information, to everyone
And you can send pictures of triode directly to this forum
I don't need to measure. I can tell if this triode is real
I don't need to measure it. I can tell you directly whether this thing is a printed triode (reprocessed triode) with my eyes
Please see my message and reply. Thank you

I bought a whole bunch of different SITs from Pras at a very reasonable price, and they all were the real deal. I bought a whole bunch of 2SJ618 or 2SK1303 from other (different) Chinese sellers - all fake. I bought a whole bunch of the ultra-rare NEC 2SJ44 / 2SK163 from yet another Chinese seller, and they were genuine alright. A lot of people here got scammed by the Chinese seller Polida... (The worst scammer that I personally encountered was in fact a Dutch company...)
Hence, saying that Pras sells fakes (without providing any evidence), or that Chinese sellers will sell the good stuff only to westerners are rather dubious claims, in my opinion.

I am from India. I bought a pair of SITs from Pras. Haven't tested them yet. But I have no reason to believe that they are fakes. Its a matched pair.
On the other hand, I had bought a lot of 2SK2013/2SJ313 pairs from UTSOURCE. All fake.

Maybe the nods can be convinced to clean up the last few days of posts. Commercial disputes are not uncommon but the seller has a vendor thread for that would be a useful place to air grievances and get redress.
Meantime if anyone has a nice circlotron using these devices, don’t hold back ����

hi
UTSOURCE
I know their staff, they sometimes come to buy chips with me, they will ask our company's chip price
This company, all the products are bought in the market and other merchants, they just have a platform, but they themselves said that they will not tell customers, only sell the models that customers need, but the nature of this product, They are not guaranteed, they describe themselves, on eBay and AliExpress platforms, customers place their own orders, so even if there is no brand new original, even if it is counterfeit, UTSOURCE is a statement, this is new (but will not say Is brand new original)
Some of their commodities are derived from the market price, they are purchased, and then sent to customers. The profits and money they earn are proportional
UTSOURCE does not have its own supply, they do not have their own goods, so they cause counterfeit and counterfeit goods (because all the chips are purchased from the market)
In addition, UTSOURCE will only sell the models you need, they will not guarantee that the products to customers are genuine, this is me and their staff, when chatting, he told me
He said: He is also not wrong, because he is selling models, not selling brand new genuine products, only guaranteed to be new

Friends of the forum, I am from China, I am in the Chinese market, if you need to purchase transistors, electronic components in China, you can find me
You have suppliers, you are far away from China, then, you can ask these suppliers to send electronic components to me, and I will inspect them for you to avoid buying counterfeit or fake products.
I won't earn everyone's money (I am in Shenzhen, China, as long as it is a supplier in Shenzhen, then I can also go directly to their store for inspection)
I have been an electronic component for 14 years, and have extensive experience. For the inspection of goods, for me, there should be no errors (the chance of errors should be 0)

Well, sir, I know it's not that easy to make SIT, so please read my words precisely, I use "transistors".
Also Sir, you are a famous DIY leader in the Western world, there would be no seller that too stupid enough to send you fake SIT.
Their marketing strategy is complicated. They won't send fake SIT to westerners, or other active DIYaudio users, so that the pandora's box kept sealed.
Why do I claim so seriously? Because we are talking about the entire ShenZhen industry, and I am perhaps kind of insider (not physically), I know a lot (eg, I even know Pras is "She").
Of course I can prove, though I might get threatens from the "gang".
However, think about it, I don't sell SIT, not a business competitor to her, why would I take risk to say things against others' interest?
For sure, all of you can still get good/genuine parts from there, from Pras, but the truth is, something like "blood diamond". The more you buy, the more victims there would be. They don't just provide/produce genuine parts, and they selectively decide and send genuine parts to world, especially Western world. But, where did the rest fake parts go?
Hello, I have never seen your reply to my message
I want to know that you have bought fakes in China, so have you found this supplier?
What model did you buy with him, is it 2SK180? or THF-51S? or 2SK182ES?
I am Chinese, but it does not mean that there is no brand new genuine product in China
I’m Chinese, I’m not selling fakes
The whole world is real or counterfeit, all because of interests and ugly hearts, and the principle of integrity of a businessman
Pras, by now everyone here understands that you deserve a good reputation,
no one more than me, since we have done a lot of business and there have been
no issues.
At this point, I think you don't need to defend yourself further.

Quick to answer emails and quick to ship!
