Dual biased emitter follower

[David White]

Based on previous advice from members of this group, I have attempted
to revise my circuit utilizing a complimentary pair, and diodes to
establish a 1.4V DC offset between the two output signals.

Here is the schematic, if anyone would please be able to comment on my
mistakes.

If you are trying to lift the common to get a starting voltage of

0 then you have your diodes in backwards.. other wise I don't see
how that actual can work unless I misunderstand what you're trying
to do here?

You've got cross over distortion, and outputs incapable of delivering
power.

what exact result were you trying for?
