Does anyone have an idea what might be the problem?

Did you measure any DC at the output?

Both end stages produced a near identical DC voltage of 0.135 volts (one
was 0.132 volts, the other 0.136 volts), which seems harmless enough.
As far as I could see, this voltage didn't drift with time, temperature,
or load until the amp broke down.
