deep101In theory the oils from your hands will shorten the life of the power tubes, so you should handle them with gloves. Sort of similar to handling your car headlight bulbs.

deep101Us tube rollers grab the tubes hot with water from the sweat on our beers. Don't worry about no gloves!!! Enjoy tubes, they are the best. It takes the hobby to an even more fun level. It's tinkering with sound made easy.

deep101The Sodium from your hands Is not great stuff for anything electronic, vacuum valves inclusive. With Tungsten Halogen Quartz lamps isolated handling is a must, for a normal lifetime. They operate with an etching of W, from the inside of the Quartz envelope, and re-deposition onto the hot W filament. This process also transfers the diffused Sodium coming through the Quartz envelope, operating at the required high temperature, to allow the “halogen cycle” to operate, distributing Sodium everywhere inside and shortening lifetime. Tubes operate at lower temps, Lower diffusion rates, and no halogen cycle to interrupt, but Sodium is still no friend, to anything inside. Older tubes had poor quality ink, so gloves are good there to protect those vintage beauties. They also assist with rolling warm tubes, don’t pull hot... cool is better. Tungsten does not “evaporate” [translation?] from the filament, it sublimates mostly with a tad actually sputtering off; otherwise Zeiss depicts the halogen cycle well. My Dad used to work for Sylvania, I though the “Halogen Cycle” was a kids story;) http://zeiss-campus.magnet.fsu.edu/mobile/tutorials/halogencycle/indexmobile.html
