New PCB's found

Hi guy's now on this forum here,

ive seen the respons on the Tripath TA2024 Chip PCBA's and i have actually found one here in Shenzhen on the local market place, it costs an astonishing 50 RMB (!!) very cheap and sounds resonable, but its not a HIFI design, lacs propper caps on the PCB but uses a nice MKP with a piggy back electrolyt of both 1 uF as input caps. straight forward design and the IC is soldered with the heat slug to the bottom ground plane for cooling, aldoh i have used a small alu heatsink glued to the top to keep its head cool at high power.

if anyone is interested in these, let me know, photo will be added later.

@ 50 RMB who wouldn't be interested 😉.
The picture will be worth a thousand words.........
 
Hi

Isn't it free, when you order above 25$, <25$ you have to pay 1.5$? Have any of oyu ordered 4 channel 100w amp that they have? How is it? Is it good?

And one more thing, prices on ebay are about 80-90% higher then on their site, there is no shipping, but if you would order few items that are more then 35$ on ebay from their site, you would for sure saved more money, coz I don't think you would pay 40$ or so for shipment. What is the deal here?

There's a thread about it: http://www.diyaudio.com/forums/showthread.php?s=&threadid=111147
Save you money, it hisses very annoyingly and noone has yet found out how to fix it (if you even can).

Are you talking about the sure electronics website? 😕
 
Hi

Didn't somebody fix this? I will go over this theread again, but I think it was solved...

2nd yes I am talking about sure electronics website, there are one prices, and about 80% higher on ebay sure electronics store. This was for several items that I looked at, not just one
 
Not every product...

The website is www.sure-electronics.net. The Tripath 15 watt stereo amp is actually a dollar cheaper on ebay once you factor in shipping. It's $24.99 on ebay and $25.99 on their web site (using post shipping).

They do have some other stuff though that's not on ebay. For example, they have a 5 FM watt stereo transmitter (ebay's is only 2.5 watts).
 
Photo's of the Tripath PCB

Okay kind of overwelmed by the response, ofcource they wil lhave to be shipped, i thing a bubble wrap should be OK, but will look in to that. ( God my GF is gonna be happy with making enveloppes haha )

euh, back to the topic, ive made photo's of a used PCB, stripped from the IC, The IC has been remarked, and i could only find out that it is the TA2024 by decapsulating it ( luckely, i work for a IC inspection company! ) aldoh on most units, i can still vaguely see the tripath logo.

the photos i made are of the PCB only, please have a look.

i took off the shrink wrap from the input capacitor, so you can see its a MKP, i measured it, ESR of 0.3 ohms, thats fair the little cap on top is really bad with a ESR of 7 ohms, i suggest replacement,
the two little caps in the middle are the rail caps, ESR is 0.2 ohms,
Good caps but way to small all the other on board SMD components are of normal quality, i could not find any major things there.

Let me know what you think about it

Greetings,

Arjen Helder
