Re: uBitx V3 low power continues

The scope traces are dim, so not sure if I am reading correctly.  To me it looks like the TP3 signal is stronger than the TP4 signal.  As David suggested, increase the scan rate of the scope (reduce the horizontal trace time / div) to get a better picture of those two points.  I would also check the bias voltages on Q911 and Q912.  That could be your issue.
