Are the tubes in the clip?
Bill: I was using no filter so my grade is about #2...
Merg: Thanks to your and Dennis' endorsement I feel confident about the new V-54 tube. I will be ordering one from Louise at the end of this week..
Richard: the tube is in the clip. But the rubber glue that holds it there has been tampered with, which makes me think that someone may have replaced the original tube. But it sure is hard to tell if it is old as it still looks plenty bright when it is on..
Thanks to all. You have been a grand help in all of this...Robbie
Robbie: Be extremely careful when replacing the tube not to stress the new or the old one. When they break you get mercury all over the place. The ones I have seen were held in with copper single strand twisted wire, but I do remember some silicone sealant too on the ends. Good luck. Good to hear that these parts are available again, after Aristo reorganized / changed hands, it didn't sound like that intended to go forward with the enlarger applications when I last talked to them. Maybe demand changed their minds.
Thanks Kevin. I have a second, very old Aristo light that is worthless and I plan to practice with that before I do the real thing with the new tube on the good head...The new one does not have wire, just clips as Richard mentioned...
The tube is strong up to a point, but brittle and it snaps like a very fresh pretzel. Not that I would make a mistake like that.
Well Kevin, you are correct! They are strong up to a point and then snap like a pretzel! The practice one I had came out like a charm. It was held in with the copper wire. But the good head I am going to use had the tube glued in with the silicon. Not so easy..snap! I am ordering the new one tomorrow and will be VERY careful putting it in. But it should not be so bad. I will not glue it in. Live and learn!! ..Robbie
