I have a standard Zone VI cold light head (not the VC version) that is about two years old.

I have had the same problem as others in this forum with VC papers not respondin g normally to filtration. I see references to the Aristo V54 tube as the soluti on to my problems. What I don't know is whether the tube in my unit is the V54 type or not. I asked Calumet, but have not received a resopnse as yet.

Does Aristo make the Zone VI? If I don't have the tube in my Zone VI head alrea dy, can I get one from Aristo that will work?

It's a drag switching back to the condenser head to print VC.

Thanks
