i don't blame you for this, there is just too many trolls & people who think
they "know-it-all" in the newsgroups.

i am sorry for being late to this post, but maybe, i can give you some
troubleshooting help with this. i made my living doing this for a long
time.

your trouble may not be from the output transistors, but could be caused by
ether a dried up electrolytic capacitor in the signal path, or a resistor
that has gone out of spec. before messing around with the output
transistors, i strongly suggest that you get a schematic diagram for that
specific receiver, a signal tracer (a audio amplifier will work), & trace
through the signal path starting from the preamp / tone control stage &
work your way up to the driver stage. this will at least tell you if &
where you are losing your audio signal.
as i said earlier, it would be in your best interest to try troubleshooting
the signal path first before doing anything at all with the output stage,
that would be the last resort.
