TK, I'm not trying to invalidate any of the good points you have made.
I was just pointing out that some valid concerns can be circumvented.
Like the good and proper concern with RC coupling having a long recovery time once grid current is present. (charged cap needing to discharge, etc)
Again, with less than enough max drive voltage to overdrive the output tube, that troublesome condition is never realized.
I have garnered a lot of negative attention while describing what is and isn't Class A operation.
In some of the text books Class A is described as not only the idle current but the load impedance and the driving voltage.
That is, limiting the drive voltage as to not drive the tube into the non-linear region of operation.
I contend that an amplifier, while under normal intended use, that allows the output tube to enter the non-linear portion of the operating curve is not a Class A amplifier.
Excuse me while I search for my flame suit. :-)
