need DIY how to convert Tukan to aktiv configurati

I am converting to Linn aktiv amps with my Tukans by buying amps with cards BUT the Tukans I already own need to be converted and Houston has no local dealer at present. Does anyone have instructions for converting the Tukans to aktiv? I have the idea I have to go inside the speaker, or find a dealer to do it, but that implies a several hundred mile drive.
