I've done the penny trick once or twice.Why so much resistance to heat sinks? Can't you walk outside and find a dead soda-pop can?
(Shortbus beat me to that one! )
Any old piece of metal will work (better than nothing) if it's flat.

OK, I see. Some linear systems need heat sinks, including an LM386, but not all."Linear" means, "linear". It does not mean, "Needs a heat sink" or, "Doesn't need a heat sink".
Yes. I can buy a Ferrari, too (a used one).Why so much resistance to thermal paste? You live in the U.S. You can buy thermal paste.
Not to be confused with silicone grease, I use Wakefield thermal compound.Do you mean that using a wad of cooking foil without thermal compound wouldn't be very effective? I assume by thermal compound you mean silicon gel or thermal grease.
Being linear does not mean that you need a heat sink -- which is why I said IF you needed a heatsink for the TIP31.I'm confused. Isn't this also a linear system:
It does not require a heat sink, although it did when the value of R3 was 1kΩ and there was no capacitor wired in series with the speaker.
Thank you. I was just about to ask why none of the Instructables I can find that use an LM386 mention heat sinks. I think I'm going to get one or two LM386s tomorrow and see how they work.I have built several amplifiers with the LM386, never used a heat sink, and never burned out an LM386. Neither I have I ever seen a heat sink used on an LM386, so I don't think it's needed.
Have a look at this thread, especially post 4; I am still using this little amp in my old truck to listen to my MP3 player.Thank you.
