Here's something I don't like the way the sch is arranged: the output stage is powered from the very first cap C22, before the R13, which will have lots of ripple. In a different radio they had a 2-pole filter with an RC after the what would be in place of C22, with a smaller resistor, and then another RC to power the rest.
I wonder if that C23 is there to counter that ripple a little.
The max C22 can be is 40uF, so you cannot increase it much.
Adding another RC between it and R13, and then powering the output from that point would be interesting.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
