Another way to remove the red coating is to rub on some adhesive tape and then just lift it off. No water and no heat involved that might damage the tubes. It should be possible to remove just the front sida coating, but it will look a little bit strange.
Another way that works on some tubes, f.ex. ZM1210, is to wipe them with a tissue soaked with acetone. If done quickly the printing may remain on those tubes, but it does not work on other. There seems to be many kinds of coating. Some tubes has a film shrunk around them, other has a thin coating as a layer the tape can lift, f.ex ZM 57?. Other seems to be painted with a dye, f.ex. the 1210. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
