As I posted here, my 5.1's won't power up after an electrical storm.  It seems that I need to replace a MOV (metal oxide varistor) in my 500 W subwoofer.  I am capable of soldering a connection, but I don't know what type of MOV I need or where to buy one.  Any advice would be enormously appreciated.

The part number is 14D181K, where the 14 refers to the physical size, and the 181 refers to the voltage. You can find an alldata sheet on it. As I recall it is 115 volts, and 50 joules, peak of 4500 amps (I'm not positive about the final numbers). It is a basic, conservatively rated protector for North American electronics.
