Availlyrics, thanks for the input. This is the picture of pcb. Yes, one of the main concern is about the ingenuity of the IC. If they turn out to be fake, I have to order directly from TI. As you probably know, it is very difficult to find a genuine ic here in my country.

Absolutely an attractive price. But, notice what is written on the PCB:
"LM1875T TDA2030A¨. My understanding of this printing is that it is either an LM1875T or a TD2030A. LM1875T corresponds somewhat to a TDA2050, not to a TDA2030A.
So, you risk receiving a TDA2030A which is inferior. OK, the price is really low.

Seller doesn't ship to my country. Not a problem though. Many boards like this one available on eBay/AliExpress.

Asuslover, They'll cost me around 2.5 USD per board. So 5 USD for 2 board. Ic will certainly be fake. So 7 USD more for two authentic ic. Some good quality cap and a bridge rectifier for psu will cost me around 9 USD. Total 21 USD without speaker protection, without replacing those otb components. So, it isn't a cheaper route. But for soldering practice, may be. Also my board won't come pre-soldered.

Hi

This Aliexpress looks genuine:

( 2 pcs/lot ) LM1875 Audio 20 Watts Power Amplifier IC, LM1875T.-in Integrated Circuits from Electronic Components & Supplies on Aliexpress.com | Alibaba Group


The cost is more than original chip selling in India from reputed distributors such as TI and Rsdeliver.

Once I emailed this seller and asked him why is he selling LM1875 (2 pieces) at ebay.com for 7.99 USD whereas the cost of the same is 12.20 USD on Aliexpress.com?

Ans: "Dear friend,
If you chose free shipping, we will use economy shipping service, no tracking number.

Thanks
Lily"

Here is the ebay.com link
