I have some audio amplifiers that are better than the LM386 for battery
operated radios.
These are the Motorola MC34119P. They are in a 8 pin dip but the circuit is
quite different that the
LM386.
These amplifiers use a Bridge output that does not require a coupling
capacitor between the amplifiers and your headphones.
The gain is adjustable over a wider range than the LM386 and they draw very
little current.
The specifications may be found at:

If you would like to try one in your QRP rig or receiver just let me know.
I have plenty.
I also have plenty of the SA615 chips that are great for making receivers.
