...at high freq, and indeed audio, this is prob true....
but, at VERY low freq, I suspect the tube has higher internal resistance.
Which means that if you are using a class B output stage, and you go
WHANG on the guitar, the B+ voltage rail sags.
Which gives one of those strange coloration effects so beloved by tube fans.

Heaven forbid!
