Seeing as how someone here has had the experience....
I used the stereo miniplug method to attach a small tape
player/radio to a home stereo/amp.
I think it happens about this time of year... when it starts getting
cold.
I could swear (and routinely do so at the thing when this
happens), the plug seems to no longer fit. IOW, it gets so the
plug is no longer seated firmly in the player's ear jack.
Anyone know why?
a. Does the cold shrink the plug (but not the jack too???),
b. the metal loses its firmness and loses springy character,
c. some strange metal-to-metal conduction effect from cold,
d. dampness (instead of cold),
I would gladly rip out the minijack and substitute a 1/4" but
there's no room in the walkman.
BTW- When connecting to amp with a longer cable, I also get
weird "short wave" reception on the AM band. (Hint: Most people
know how the earphones to walkmen act as antennas--BUT
THAT ONLY APPLIES TO FM. Also, few radio portables seem to
bother with AM antennas.)

I agree with Jim on size. The 1/4 phone jack has long been
standard
for audio patching. The nice thing about that standard is that
you
can find many sources of these ready made or custom made.
Personally, I prdfer to spend time on circuits and leave the
cable
soldering to somone else. I just soldered so many in my life, I
would rather not.
Now, whether you use 1/4 mono 2 conductor, or 1/4 3
conductor TRS
(tip, ring, sleeve) often called stero, really depends on your
application.

andrij,
I'm building a couple simple audio circuits, but want to be
able
to use
modular input devices.
Larger jacks are better unless you plug them in only on rare
occasion.
