uBitx amp is single ended part of stereo amp. It is not bridged!
One lead is ground and other goes to output cap.
In bridge both outputs are used and cap may not be needed.

Read the thread/s thoroughly, Raj (and all). Shorting the output keeps both legs of it above ground. It would seem that taking either leg to ground (that 'ring' connection that is taken there by a mono plug in particular) does the damage. It's the 'cheapo' method of boosting audio output: bi-phase two amps: 4x the power from the same supply voltage. This package evidently does this internally. If the spec sheet shows the internal circuit, this becomes obvious. I await reports...
