Wow, you have slipped up with this philosophy in this case.
I would be extremely cautious with the LM386. I found this out recently when I built this project that uses the LM386:

I had to acquire a genuine vintage LM386.
The originals could tolerate a high capacitive load on their output and were completely stable.
The new generation clones/copies/fakes ( and that is being kind) out of the far east are "hopeless" and unstable.
Occasionally you will find genuine vintage LM386 for sale, but they are getting a lot rarer and sellers know this now, and they are more costly.
The reason this has happened is the popularity of the part, so a plethora of poor quality fakes has flooded the market diluting the real ones near out of existence, as if they were a grain of slightly different colored sand, thrown on a beach.
