There seem to be a lot of threads where people suggest that the PT2399s they bought from Tayda were noisy or simply non-working. I haven't ordered from Tayda in a long time, but I need to this week and was wondering if I should throw a few in. I suppose for the price I can afford to experiment.
Are there multiple manufacturers of legitimate PT2399s? If not, are Tayda selling clones or work-alikes (or fakes)?
I ordered 10 of them a while back, have used 4 or 5 with no problems. For the price, it's worth the gamble, even if you get a couple of duds.
I just ordered a few as well. Having heard various things about diff PT2399's, I checked around and at like $.50 vs $2-3 at other places, it was certainly a no brainer. Haven't put them to use yet so I can't speak to the quality.
Just put two in my multiplex. They sound as good as the others I've bought.
I've bought 3, all working. I have a suspicion all of these complaints of non working chips are ESD related tbh
Great! Thanks, everyone. I can can certainly risk a buck or two on these, especially since I know I have to order from a couple other suppliers soon anyway.
I've bought 12 from them. I've only tried 4 or so, but they all worked fine.
Now if only they would carry the surface mount version (I did put in a request).
I bought 2 from Tayda, both tested in the same circuit, they both work. I'm never sure about the "noise" that people hear with PT2399s, but I don't believe I hear any extra noise brought about by the chips.

You would definitly hear it, cracking in the repeats, inconsistent......
The last time that i bought PT's from Tayda i got 50 of them, i have around half of them used now and only 1 seemed to be defective but i think it was blown by a bad working 78L05 Vreg....
Changed the Vreg for one that i tested before installing, still had a background noise, swapped the PT and it was all good.
Bought 3 of them a while back. 1st one I popped into my Sea Urchin worked perfectly, so I haven't tried the others yet :) Those are destined for the Multi-Plex.
I got a batch of about 10a month or to ago and they were all good. Of course these are the only ones i had. Some seemed more effective in-circuit, or seemed to sound better. Might be placebo
Don't think we've ever had any duff ones (just slapped 4 into a pair of Multiplexes no probs).
It looks like Tayda is substantially cheaper than places like Small Bear. Is there a reason not to order stuff from them (other than supporting a small American business vs. a Thai business)?
Tayda's a solid company to order from, and you can't beat their prices. I've placed at least 7 orders this year with them, no bum components to report. Typical shipping time is a week and a bit, so even that doesn't work against them. And if you can catch one of the 15% FB promos, even better.
The main reason perhaps to go with Smallbear is that they carry more specific parts that Tayda doesn't. The variety that Smallbear carries astounds me. Granted, some of their prices are more expensive, but they do have a different level of overhead compared to a Thai company. I find that Smallbear is my favourite place to get Pots and the hard to find extras. I get passives, ICs and transistors pretty regularly from Tayda. PPP for enclosures for sure. Mammoth has been making headway for me as well.
One stop shop? Tayda's not quite there yet. Smallbear is still the closest for one stop shopping.

You can buy them relly cheap in Canada .http://www.ebay.com/itm/10x-Digital-Echo-Surround-Processor-PT2399-SMT-DE4026-/221137528177?pt=LH_DefaultDomain_2&hash=item337cd2e571 (http://www.ebay.com/itm/10x-Digital-Echo-Surround-Processor-PT2399-SMT-DE4026-/221137528177?pt=LH_DefaultDomain_2&hash=item337cd2e571)

Have you personally tried these? A lot of the PT2399s on eBay are fake. Some of the SMT ones aren't even the correct IC package. The fact that this ad uses a rendering instead of a photos makes it difficult to tell.

After my recent issue with eBay PT2399's., I don't even trust the photos that show real chips. The through-hole ones I got on eBay had a photo of a chip that said "PTC" PT2399, but the ones I received had "DTC" printed on them.

Blake wasn't that your thread over at BYOC you started? Some good responses in that one too.

Yep, that were me. I ended up coughing up the extra cash and ordered a handful from Mammoth. I've only used one, but so far I've had no problems whatsoever.
Sorry to jack this thread, but as i was reading it, i realised i have never checked tayda out, assuming it was US, as i'm UK, shipping is expensive, but the prices there seem ridiculously cheap, and the shipping seems reasonable!
Do any of you guys have any experience ordering to the UK from them?
thanks
George

I am USA not UK, but I have to say my shipping experience with Tayda has been almost unbelievably great. I purchase the cheapest shipping method, DHL, and they quote 15 day shipping, but it usually arrives in 5.
But it has to be remembered, Tayda now has a wharehouse/shipping center in the USA now. So our North American experience may not translate well for UK. BUT when my Tayda orders came from Thailand, the shipping was still fast and the prices are great. They sent me perf instead of vero once, but I will eventually use it.
i usually order mine from Mammoth or SmallBear
I've gotten a bunch from mammoth and Tayda and haven't had any issues that weren't my fault.
I know this has basically already been said, but PT2399s are known to be inconsistent. Unless someone specifies that they are selling tested units, there's no reason to assume that any supplier is selling you something different than Tayda. There are some ebay sellers who might sell counterfeit chips.
Of the 19 or so PT2399s I've bought from Tayda, I've thrown away three of them for motorboating, two are marked for breadboarding only (some motorboating but not bad enough to trash), and four that I got recently haven't been fully tested yet. None were "nonworking." I didn't have a problem with the two I got from Smallbear, but that could easily be the luck of the draw (and in fact I soldered them without even testing them so I got really lucky).
I like Smallbear and order from them often, but Steve doesn't, so far as I know, test his PT2399s (or have them tested, like his JFETs), so given that I've learned my lesson and I'm socketting or testing all my PT2399s now, even if he did test them, $4 is SEVEN of the same chip from Tayda. No chip has an 80% failure rate. I think a couple people just had really rotten luck.
I've got some of those "DTC" marked ones and of the few I've tested they were fine. Lower noise floor than some of my others from Tayda. Considering the cheap prices you can get through Tayda and eBay it just makes sense to get a bunch of them and sort out the bad ones. I cannot see paying $4 for a PT2399. However, Steve most likely gets his through a broker which probably gets them directly from the manufacturer...so I doubt he ends up with any fakes, clones, etc.

I've
heard that Smallbear tests theirs, but I haven't seen anything about it on their site.
I think I may just be one of those that has had rotten luck, considering the number of members on this and other forums who've had little to no trouble out of Tayda's chips. I certainly order lots of things from Tayda on the regular, so may just buy $5 worth next time to test my paranoia (it's certainly not a huge gamble price wise).

That's actually pretty reassuring. I don't care if the "DTC" chips are not genuine PT2399's so long as they function the same and don't introduce any funky noise.
Which begs the question: Is there really any profit gained by faking an already inexpensive chip, and what is being used as the fake? A counterfeit MN3005 makes much more sense given the value of the real ones, but these leave me a bit baffled.
its always a gamble on electronics. Thats why i never buy just what i need, I always +1 - +6 things. Especialy those harder to find parts. Besides you fill up your parts drawer that way ! ;D
