partial bootstrap

Hi,

Here is a partial bootstrap variation. I noticed in simulation
that Q1 had small negative base current on the tips of the negative
swing of the signal. Also wanted to eliminate the compensation. So
here is one approach to the problem. Other ways?

Gain at 1Khz = .955714, -3db = .675690
-3db frequency = 2.7062Mhz which is still way out past the single
emitter follower.

It is more linear than the single emitter follower case and doesn't
require any compensation. Not as linear as the Sziklai.

Thoughts?
