...can be significantly reduced thru judicious use of negative feedback. See attached plot from D.T.N Williamson's article in Wireless World. I'd also predict LF "ringing" @ 1-2Hz based on this plot. The circuit this plot is derived from has a tc ratio of about 1:1, much less than the 10:1 rule of thumb.
