Dear All
we have made a amplifier based on TPA3250
PVDD is 36V, Load is 4ohm, out put is coming 125W; PVDD capacitor is 2200MFD/63V
We are facing one issue
when we switch on the amplifier ..it is giving a loud sound " Thuk",,
It comes only once.....when set is on./...after that it is ok.
when we kept set off for 30/40minute...and switch ON again. It comes up again
if we switch on /off set frequently...then it does not come.
pl suggest, the reason of loud annoying noise
