Not exactly. It allows a high value collector load on the first
stage, but low impedance output load, due to the follower. The
follower also provides drive to the feedback R without loading the
gain down.


I'm not quite sure what circuit you're talking about.

AoE2, p.872.


That's the once-popular "GE circuit" mike/phono/tape head preamp. R5
was usually bypassed.
