Mouser sells the NJM2073D, seems a reputable manufacturer, should drop in for the TDA2822
There's also the $0.29? UTC? TDA2822 clones on Tayda, they apparently work fine according to reports in the forum.
And the NTE7155, possible to buy but not available from mainline distributors.
Here's an interesting examination of alternatives to the LM386:

Regarding Olaf's request for a more modular approach, I wouldn't do anything
that complicates assembly or impacts the cost.? But might consider additional feedthroughs?
or the strategic use of through-hole components such that the standard parts could be removed
from the uBitx board and some little daughterboard soldered in place on header pins.

In the meantime, we have to look for alternatives to the TDA2822. I am highly inclined towards making a discrete device amplifier. We will never run out of discrete devices, the audio would be so much better. Does the gang have any ideas?
