Jan,
The omnadrens you said were fake, are they from Poland? I just came across these Jelfa Omnadrans and they look down right BUNK. I'm assuming they are the same. 2thick said they are the old ones. You said something about a link around the neck and the real ones being taller. What's a "link"? How can I tell if mine are real? There is no label on em, just printed on the amp itself. If you need more info on what they look like, just ask. Maybe if you got pics? Thanks.
