I am trying to figure out what this board is. I got one, it is apparently a PBTL 7498. It is advertised by Ebay sellers as a 20hz to 20khz 140 watt, but it obviously doesn't get much above 300 hz. Been buzzing out and found a way to remove two capacitors then run 30ga wire to my variable span low pass filter. It was then I found it is not the 100 watt TDA7498MV mono version. It appears the A and B outputs are parallel, so my input wiring may not work as expected.
So I'll have to keep digging until I find what this configuration is. I wanted an amp to use with the adjustable low pass filter I have. I am beginning to think it is 140 watts with a 4 ohm load, configured parallel. Looks maybe like another cheap class D amp going into the use it later box.
