                        <content:encoded><![CDATA[Except that whenever any amp's being overdriven it's no longer running in true Class A conditions.

Depends entirely on the definition of over-driven and how the bias is set. The transfer characteristic of a class A amp can be very non-linear well before clipping of the waveform affects the bias enough to turn off the active device (tube or transisitor) during part of the waveform cycle. The bias might also be adjusted so the clipping is not symmetrical -- that could keep the device 'on' 100% of the time at the onset of saturation and well into the soft clipping of one side of the waveform.]]></content:encoded>
