Default Another cheap TA2020 board

Does anyone have experience with this TA2020 board. It is the cheapest atm on eBay.

DC 9V?15V TA2020-020 T Class Digital Amplifier board 13W+13W/20W+ 20W | eBay

The caps used are the cheapest on the market. I have access to a lot of caps so a mod wouldn't cost me a thing. I want to use it to drive some ceiling speakers that are nowhere near hifi.

If it looks too good to be true it probably is.

Since when did the TA2020 have "gold" pins?

Do some google research. There might be fake TA2020 chips popping up.

The price is low enough. It might be worth a try. Let everyone know how it goes.

It might be good enough for the purpose you have in mind.

Purchased it, I have another YJ board so I can compare them.
I don't think the chip is fake but it could be possible that another company reproduces the chip.

I've tested the board with Wharfedale Diamond bookshelf speakers. This board is weird to explain. It is very stereo rich, no idea how that is possible. Sounds like it has some sort of 3d effect in it. Lacks a bit of bass, probably cause of the low quality input caps. Power consumption is almost equal to the YJ board. I do think this board has potential.

I just bought this one too: MKLL TA2024 Fully Finished Tested PCB Power Amplifier Board 2X15W | eBay

I never heard a TA2024 so this will be a nice competitor too. And god damn these became cheap, last time I checked they were twice that much wich wasn't expensive either.

Gee ...How surprising
As a good guess: even the TA 'chip' is some inept copy.
