Thank you so much doctormord,
in that site I had seen a tpa3251 4-channel 100W
there are consistent differences in the sound of 3251 and 3255?

Hello @zenit70,
here is the 3rd-audio PCB, which doctorMod mentioned.
TPA3251 2x100W + 1x200W 3Ch Class D Audio Amplifier | eBay
I have the 2-channel version and I am very satisfied.

The term is used for generic China boards from no specific vendor.
if i understand you right....no there are no extra holes to hold the chip down.
just the big ones for the heat sink to push the chip down to the pcb.
can you show a correct imlementation with a nice pic?...please...thx
What i mean is, that i can't see any through-soaked solder at the vias coming from the powerpad at the other topside.
hi doc
yes this is correct i remember ...no soldering soak through this holes.
tpa3250....fx502spro
is it possible to rework (solder) this easy? i guess not....
Hi!
I am in the process of building a six channel TPA3255 amplifier (three "chinese" tpa3255 modules with three switch mode supplies).
I would like to use a speaker protection and turn on delay module.
I have some UPC1237 stereo protection modules at hand, however, they use a common ground between the left and right channels.
Is that ok for the bridged stereo TPA3255 module, or will I have to use seperate modules for each channel?
Thank you,
Arndt

But I already have four of those modules, bought especially for my setup.
The big SMPS is for an additional IRS2082 subwoofer amp... I need to fix a bent cap, so it is not mounted right now.

thanks for your quick response.
If i look at the TI LC Guide.....Your output filters are 10µ but 680nF
is it a compromise for 6 ohms?
