Can anybody identify this? I'm pretty sure it's a fuse, maybe 4 amps? Fast blow? Thanks for looking. http://i.imgur.com/2gARGQ0.jpg

Looks like a fuse to me too. 4.00 amps. European?
No idea about fast/slo blow. Any other marks on it? 'Cm g' is not easy
to search...
Any clues as to where it is found in the equipment? Is it open? Did you
try a diode test to see if it only conducts in one direction? How about
20M Ohm scale - anything?

I'm not familiar with resonators, no idea how to test it.

The prevailing theory seems to be its a ceramic resonator. It has a fair bit in common with a capacitor, and a capacitance meter should give a reading you can check against the data sheet. The difference is; the dielectric is piezoelectric and its physical dimensions give it a resonant frequency.

Several suppliers include application examples in their catalogues. Maybe the simplest would be an oscillator built around a 4069 or similar. The fact of whether or not it oscillates would be significant, but if you have a scope and counter ready to hand, it can't hurt to make sure everythings right.

That case style looks familiar - might be MELF. That info could save some time searching the catalogue.

One I'm certainly well aware of is the ceramic filters and traps that were used in TV IF strips. The parts look almost identical, but one is a filter that lets 6.0MHz (or 5.5MHz) through, while the other is a trap that passes everything except the marked frequency. Most often they were 3 terminal types, but there were a few 2 terminal types. and ceramic filters peak at a slightly different frequency depending whether they're series or shunt connected.
