Default The EasyWay AMP

In this project
you can see an inverting power amplifier
with:

a) only 4 stages
b) common base VAS and
c) low gain output devices

input impedance is low
so need a Op-Amp preamplifier

ideal gain is G=10

the 24s and 25s are reversed.

You're not running much current through the input transistors. How do you expect to develop any voltage across the 150Ω resistors?
