Sub for tube stuff! Argentina

What I have is a Radio Shack 12" dual coil subwoofer Cat# 40-1350A...It was part of a planned isobaric push-pull project...needless to say I just used one...with great results.
The huge chokes I used were very expensive...so the isobaric was out.
Currently I'm into tube gear & I'd like to trade it for any and all tube stuff. I'm currently residing in Argentina so I need someone from this country to trade with...the import duties here are some ninty percent of value so outside trading won't work.
