I've always sort of liked the classic "GE" tape head/mic preamp

but it occurred to me that it might also make a nice headphone amp....

Audio tends to be nonsense, but at least the audio guys have fun
playing with circuits, whether they make a lot of sense or not.

Along with the hundred other things a boy can do with a 555.
So someone has used a 555 to make a less than impressive radio-
receiver. Why would anybody be interested, if they hadn't fixated on
the device early in their career and never moved on?

For the same reason people build ships in bottles, when you can build a
far more durable working model much more easily by heaving out the bottle..
And the same reason people compose sonnets, and even sometimes fail to
cheat at solitaire.

So you'll know what to do when,
You're stuck on a desert island with three cocanut shells, some wire
and a 555 timer.....
Seriously I don't use the 555 anymore, but we have several old
circuits still using it. And I hope it and the 741 have only reached
middle age.
