Thanks for all the responses. It does look like it's an inductor, and
it is magnetic (wouldn't have thought to try that :)). Now I know, for
future reference.

So I'm
cleaning out the Ergo 201 terminal I mentioned earlier (and
preparing to do a cap kit on it since it needs it) and I've run across
something that looks kind of like an electrolytic capacitor on a diet.
I'm unable to identify it and I feel like an idiot :). At any rate, it
appears to be leaking something so I'd like to replace it, once I can
figure out what it is. Wish I had a schematic for this thing.
Here's a couple of pictures of it:

Any ideas? The only markings on it are:
1019
8320
TWN
on one side, and
C-H-L
TDK
It looks like an inductor, and TDK are of course known for
(electo)magnetic stuff. The only puzzler is the polarity marking.
Now, as you may know, ferrite cores can saturate, so that the inductance
of a ferrite-cored inductor depends on the current though it. And there
are such inductors with a permanent bias magnet, so that the
curent-inductance characteristic depends on the direction of the currnet.
And yse, such components are commonly used in monitor, and thus terminal,
horizontal deflection circuits as linearity correction devices. Some are
adjustable (the magnet can be turned to alter its effect), some are fixed.
The only thing is, I've never seen one with a polarity marking (often
they pnly fit the PCB one way round), and they're normally larger than
the comopneent you show.
But have yo tried to see if it's magnetic? Will it attract a
non-magnetised tool?
