Thanks for posting. To me that ebay item is BS. Kind of like those "1000 watt quad channel" car stereo amps you find in a flea market, that when taken apart reveals a single 20 watt amp chip, with all 4 inputs and outputs joined. The chip is not rated by the manufacturer for that power rating, so its an exaggeration . Who wants to buy from anyone that lies about technical specs.

Plus, for the small convenience you get for having terminal screws over solder connections, is not worth paying 3X more. this link still has the best deal I've seen on a YDA148 based amp, under $10!

They are the same specs. Just wondering how good or bad is this amp.
The board I posted I found out yesterday and seems much like this one Goodfortune/好运来R7功放机 YDA148 30W*2 发烧功放板-电脑硬件/周边/网络设备-电脑多媒体音箱 | 网购-拍拍网 which is also at dx electronics.

I also changed the small aluminum caps with some nichicons same value from the told series, but not much improvement, a little more detail n highs, also maybe changing the inductors with some wurth, but this haven't try yet, someday I might... But changing the 2200uf CAP for a 4700uf one made the biggest improvement..
