Can you touch the tubes?


I was talking to someone at the tube store about replacing some KT 150 tubes and he said it was perfectly fine to touch the tubes.

I've always thought you're supposed to handle these things very carefully with white gloves or a microfiber cloth.

Handling them with my fingers makes it easier to pull them out , insert them more securely.

Does it really matter if my fingerprints get on the glass or should I clean them off with a microfiber cloth after I touch them?

I had metal halide bulbs over s fish tank.  The fixture had a safety glass.  When a bulb exploded (near its end of life, a common occurrence) a few glass fragments were so hot they fused with the safety glass.  I’ve also had tv projector bulbs explode (also metal halide).  As I explained above, failure from skin oil happens with such bulbs because the oil carbonizes from the heat, turns black, and the black absorbs the high intensity light instead of letting the light pass through, and it is this additional heating from absorbing the light that causes failure.  Even if a carbonized black spot did develop on a tube, it doesn’t give off enough light to cause overheating; the tube will NEVER fail this way.  I’ve seen tubes marked by permanent markers; there is no harm from this.

That's also why you're never supposed to touch headlight bulbs when you are installing them.

I heard that licking the tubes will give you deeper sound stage, and better channel separation!

but you can only lick them counterclockwise

Ahhhh!!! A man of experience. Lick one tube and you're a tube licker for life. You and @tubebuffer must be related.
