HI, i present you "Mona", it uses bd679/680 as output transistors.
They are 40W darlingtons -> Q1+Q4+R1+R3 simulate bd679.
same for the downer side.
I forgot a cap in the fb, for DC protection.
Greetings, any oppinions would be welcome.

Q5 and Q8 collectors are dangling.
J.
yes
i use their junctions as diodes as vbe, they are mounted on the heatsink.

Which still means collectors are dangling... because unlike simulated transistors, real ones have a limit to Ib.
But since you are into transmitting while talking to yourself, who cares.
little update:
output transistors bdx53c/54c are suitable as bd679/680.
mj11032/33 are for simulation only (their beta is changed in the simulator).
distortion is less without input LPF
This time adjustable bias
from 4 to 114mA
