I am still waiting for the other two to pay, so I have not placed an order to purchase components, mainly because the AK4137 is really too expensive. If I have not received the money, I dare not buy two more AK4137s.

Payment sent.

Can you please add me to the list with AK4137

 

[yunyun]

If you can pay right away, you can replace the quota of those who have not yet paid. I will send a PM.

This group buy has been closed now. You can join the next group buy, but the next group buy requires more than 10 boards. If you are still interested in participating in group buy, please leave a message in the forum to show that you are interested.

As shown in the screenshot, I have completed the purchase of components for 5 boards and purchased them from two sellers respectively, in order to be able to buy the cheapest AK4137. It can be seen from the screenshot that the component purchase amount is 2314RMB (almost US$350). It costs about $53 to make 5 boards by SMT. I have no profit.







Two days later, after the components are sent to the factory, the factory will start to arrange production, which will be completed in about 1 to 2 weeks.

I will ask the factory to make more blank boards without any components. These boards will be sold for $10 each.

Thanks for putting this together yunyun!

yunyun, it is very important to use the "correct" SRC4192 in this construction.
They come in two different types from different factories.
Glossy and matte plastic. Only suitable with matte finish. Glossy ones are much worse in sound.

It is matte:

Is the SRC4192 in the pic an old one you already had?

In the previous photo, new, matte. He is good.
But glossy (bad). From the Chinese board.
I sent the glossy chip to the trash can.

 

[yunyun]

Thanks! From the photos, it is difficult to distinguish matte or glossy. However, I have asked the seller to provide photos, upload them later, and then help with identification.

The seller is a large seller who specializes in helping the factory to distribute components. The source of the goods should be reliable sources.

The SRC4192 is purchased by GB, such as the photo, is this OK?

@yunyun: could I join albeit late the GB please ? I am interested in 2 boards please

cheers

Since I got the photo of SRC4192 recently, I need to confirm whether it is OK, so the time for purchasing components is delayed by one day, so the additional order is currently open temporarily for 5 hours. After receiving my notice, please complete the remittance immediately. You can't let other people always wait for you, right?

In other words, after 5 hours, you can only join in the next GB. Thank you for your cooperation.

Thank you @yunyun !!

I will try on to not let other people wait for me, so paid in full right away. Thank you very much for accommodating me, truly appreciated.

cheers

Hi PPY,

Just curious, how can you tell the difference between good and bad just based on the photos?

Hi yunyun,

This GB run very fast. I haven't access to a PC these days, so I was late to the payment.
Anyway I'm interested in the next GB... so please count me for a one assembled board (including AK4137).

 

[yunyun]

This is the quotation from the SMT factory. I will purchase a total of 20 PCB boards and complete 8 finished products with SMT technology. In other words, there will be 12 bare boards that can be sold for $10.
