Vintage MIT Terminator 2 speaker cable

Hi, i need to know if there's something to do for this cable. One side is dead, not working. Called MIT, they said too bad no fix for this buy a new one we give u a discount. Well... no thank u. I think I read some on the web people that opened the box and did something. Do u people know anything about this cause I'd love to get them back on track. 



I took mine to the office and threw them under the x-ray. Looks like nothing but a peewee inductor soldered in there on the positive wire. I'd try popping that box open carefully and see if you can find a connection that came loose. If you can't fix it let me know and I'll post my old set on Audiogon cheap for you.
