Help identifying capacitors

[driblio]

Hello,

I'm trying to repair my speakers, and i need to replace a cap in one of the crossovers. It's a ceremic disk type, but it's not very clearly marked...

On one side it is marked:

PF6S
MEXICO

The S could be a 5, but compared to the one on other side, it's more like an S

On the other:

X60
X050

Although the first X is sort of on it's side. See the attached pic.

Any ideas what that means? I have one good one - any way I can test it's capacitance with a simple (V, A, Ohms and transistor tester) multimeter?

Possible test

If you have a function generator to go with your multimeter, you could get an idea of the capacitance.
Feed an AC sine wave into it at 10KHz with voltage of maybe 1 V.
Measure the current.
Use Ohm's Law to calculate the reactance --> Xc = Voltage / Current
Use the reactance to calculate the capacitance --> C = 1 / (2*pi*freq*Xc)

Example:
-------------------
1V~ @ 10000 Hz generates 0.23 mA of current through the cap.
Xc = 1V/0.00023A = 4347.826 Ohms
C = 1/(2*3.14*10000*4347.826) = 3.66e-9 == 3.66 nF

BTW, I just picked 10KHz from thin air - feel free to use a different frequency.

I read it as PFGS 60 X050. I think it will read close to zero on an ohmmeter.
I think this is a PTC fuse rated at 60V 0.50A protecting the tweeter.
I'd be surprised to find a ceramic cap in a crossover filter.
