Whose Martin and will he know how to get the parts I need? There seems to be no one else asking the same Questions I have!

I have moved and lost parts to this speaker, and one of the fabric panels is damaged. I am very low tech, so please help. I can't find what plugs, cables etc go with this speaker, or the pedestal for using it on a table. How do I locate and buy these? Also, is there a way to fix the panel or find a new one? Thanks so much for your help.
