what do you use to remove your tubes?

Happy Holidays! ! ! I want to pull my preamp and signal tubes (12AU7's and 12AX7's) to see what brand they are. They only stick out of my Rogue Cronus Magnum about 3/4 of an inch. Do I have to use cotton gloves / towel or could I use latex gloves? I'm thinking I could get a better grip with latex gloves. Once I know what they are, I would like to post a thread on what other tubes people are using in their Cronus Magnums and what effects they are having on the sound.

Jea48. I pulled them and the preamp 12au7 is a Sylvania. Out of the other two 12au7's, only one of them I could read '12au7'. I got nothing off of the 12ax7's. I think they're probably all Sylvanias. I think I'll shoot Mark O'Brien from Rogue and e-mail and ask him.

I'm considering rolling the 12ax7's. Not because I'm unhappy with the sound, but because I've never tube rolled and would like to hear the differences for myself, as opposed to reading other peoples description of the differences.

Try a 7025 in place of the 12ax7.This swap worked great in my Rogue TempestII.I used an Amperex 7025.

Amperex (Bugle Boy) and Telefunken work great in other preamps I have.Make sure if you get Amperex,get the Made in Holland labeled.Since Richardson bought their name,there are all kinds of budget Chinese (plus who knows where) made Amperex tubes out there.Nos RCA's are ok,but may not perform better than the Sylvania's that you have.They're good tubes too.A link may help some.♫Link>>[http://www.guitaramplifierblueprinting.com/tube_makers.html]

I don't know about the accuracy of the link above,plus its 4 years old.New Sensor owns more brands now I believe.
