TPA3250: DC blocking Electrolytic capacitor on the output lines for TPA3250 and TPA3255

Hello team,

We are currently using TPA3250 and TPA3255 in PBTL mode.

We have a transformer connected to the output for stepping up the output signal.

Could you please clarify whether the DC blocking capacitor ELCO (C21, C34, C42, C56) are required for PBTL mode.
