My guess is Thermistor, they are rated in terms of resistance. There are some 3.3 ohm ones for sale at DigiKey but not in the same package. MOV's "metal oxide varisistors" are rated in terms of voltage and current. This page might help shed some light on the subject.
Thermistors - PTC | Digi-Key
Is there a way to scan and post the schematic?

The third part down on this list from Mouser might be a good choice, without knowing the specifics of what is coming out of your speaker terminals. The rating is (3.3R) 60V and 4A, which should cover a lot of amps

Suggestion: if it were me, I would buy two and replace the one on the other channel too. Since this one went the other probably won't be far behind (age), plus they will match.
Good luck!
