There is one other thing that came to my mind. If I read this from TA3020 reference board document:
No damage will occur to the TA3020 if either the V5or VN10 collapse before VPP or VNN, assuming the mute is asserted before the supplies start to discharge.
Then I have to assume that a damage could occur to the TA3020 (or the MOSFETs?) if I remove power WITHOUT mute asserted. Is that correct? If so, then I have to check for a faulty TA3020 or MOSFET because I did exactly this on both amps.
