Hi all, I have a bunch of old tubes which have not been stored properly. I want to clean them up before checking filaments and then offering them for sale or trade to hams. I expect this topic must h

Are the tubes all glass or do they have any metal or ceramic portions? Glass cleaner should clean all glass tubes. I clean silver plated copper and brass with "Tarnex" silver cleaner and I wash it of

I have a friend who called me one day. He cleaned all the tubes in his HRO-50 with window cleaner. The reason he called was because the cleaning fluid removed all of the tube identification. He asked

If you have lost the tube markings on the tube envelope, try this which I remember from years ago. Put the tube in the refrigerator, cool it down, then bring it into a warm room temp environment. The

I have always used near pure isopropyl alcohol, which I obtained from an electronics supply house, and Kleenex. You need to be real careful wiping to avoid removing the lettering but the pure alcohol

Breathing on them may work. Another old favorite is rubbing on your hair. A strong light helps in both cases. A nice thing about the HRO-50 is that there arent many hard choices. The 6V6's are easy a

If you look on the rim of the metal tubes near the crimps that hold the Bakelite plugs on, the type # is usually stamped there on the rim. Randy AB9GO "In theory, theory and practice are the same thi

Don't get glass cleaner or even water NEAR the tube if you have any desire of saving the nomenclature that is printed on the envelope. Just use a dry cloth and carefully wipe the envelope. That works
