Sure Electronics Tripath boards?

[Bare]

Could?? be the Fake Clone Chinese "Tripath" Chip??
Tripath closed it's doors... in say what 2005?

Ofc that's a possibility. High possibility.
But if they made tripath clone chips like this, it means they almost succeed..

Anyway,

Before inductors there is 800khz after inductors 50khz still there without any signal...

The 800kHz is correct for the Class-D Tripath switching. The 50kHz is likely an ocilation somewhere outside the chip. Maybe an opamp buffer or some other active part that's not the TA2020?

Hi Pano,

It's sure ta2024 board.. There is no active part other than the chip itself..
Seller sending another board btw..

Thanks for the info. I never had a TA2020 oscillate on me, so can't be much help tracking down the problem. Good that you are getting another board.
